Structural MechanicsRealize Your Product Promise

Structural integrity is one of the most criticalconsiderations in product design. Acrossvirtually every industry, product developmentteams must ask and answer foundational

questions such as How long will this productlast under daily use? and What are thephysical forces that can cause damage? Thereare unlimited what-if questions as well: Whatif I trim the thickness of this material by amillimeter to reduce raw material costs?

Whatever your industry or application, yourcompany faces enormous pressures to makeproducts that are stronger, longer lasting andpacked with customer-requested features. Atthe same time, the bottom line dictates thatyou drive time, costs and risk out of the productdevelopment cycle while creating ongoinginnovations that position the company formarket leadership.

How can you and your engineering team meetthese conicting demands? The answer lies inleveraging the power of engineering simulationto design and verify products in a virtual,risk-free environment, minimizing the need forphysical prototypes and tests. With its powerto slash money and time from the developmentcycle while still ensuring a high degree of

product condence engineering simulationhas revolutionized structural engineeringover the past four decades. Structuralmechanics solutions from ANSYS have led thistransformation, determining how underlyingmechanical physics forces aect overallproduct integrity.

ANSYS: Shaping a Multitude of New Products

In the product development sector, structuralmechanics forms the backbone of productdesign. Engineers in virtually all industriesare leveraging ANSYS solutions to solve large

and complex simulations, supporting the dualchallenges of speed and high-impact innovation.

In the aerospace industry,engineers rely on solutions

from ANSYS to explore the strengthand durability of lightweight composites

and smart materials, which can improvefuel economy. Advanced capabilities makestructural mechanics analysis fast enoughto apply to vehicle structures, landing gear,wheels and brakes, gearboxes, and other criticalcomponents. Researchers investigate bird strike,crash and impact scenarios through explicitdynamics tools. Multiphysics capabilities studymore complex issues, such as the performanceof conformal load-bearing antennas integratedinto the fuselage. Our products are instrumentalin helping aircraft companies achieve their goalof zero rework, accelerating the developmentprocess and reducing design costs while enablinginnovation, creativity and quality.

In consumer products, engineers use oursoftware to perform materials stress and fatigue

tests, product drop tests, noise studies and othercritical analyses that ensure a range of consumerproducts from cell phones to washingmachines operate as expected, minimizingwarranty costs and manufacturer recalls.

The automotive industry applies ANSYS to abroad range of applications, from cars andtrucks to agricultural equipment, high-speedrailways and workhorse construction vehicles.R&D teams ne-tune the internal combustionengine to increase eciency while reducing

pollution; they also study structural integrityof engines built with new carbon ber-basedmaterial. ANSYS tools optimize designs forimproved aerodynamics and weight reduction

by eliminating excess component materials.Whether the application is single-physicsstructural analysis of wheels, arms andbooms or a multiphysics electromagneticthermalstructural modeling of advancedsensors and actuators, our tools are heavilyused in advancing rapidly changingtransportation technology.

By combining ANSYS hallmarks of depth and

breadth with speed, exibility and high delity,

our solutions are setting the pace in structural

mechanics simulation.

We use ANSYS as a virtual laboratory, since its quite

expensive to build experimental devices to conduct

testing. ANSYS code is really close to the actual physics,

and it assures you when something is a good idea

and demonstrates clearly when a design fails. Its

simply the best code when you compare all its features

to other software.

Industrial equipment robots, lathes, millingmachines, separators plays a backstage roleto the materials and goods that make modern lifepossible. Competitive economics and consumer

demands dictate high production rates;discerning businesses and consumers requirehigh-quality products with tight tolerances. Bydesign, factory machines have high inertial loadsthat require accurate consideration of dynamicsand resulting stresses. Industrial machineryskey parameters include small size and low weightbut high strength and reliability.

In architecture and construction, the structuralintegrity of any building is only as good asits individual parts. Civil engineers integratethe pieces into their building designs; at thesame time, they must comply with increasinglydemanding safety, government and greenregulations. Our tools give designers the abilityto assess a range of variables in a virtualenvironment, whether the application is high-risebuildings, bridges, dams, tunnels or stadiums.

The energy eld continually nds new waysto leverage the power of ANSYS engineeringsimulation. For example, researchers use ourtools to model and improve the entire coal supplychain, from mining to combustion systems and

power generation processes. Other sectorsleverage the advanced technology whetheraddressing nuclear power regulatory compliance,drilling for oil and gas, identifying optimalmaterials for wind turbine blades, or retrottingexisting equipment.

The Need for Speed

As product designs have grown in complexity,structural mechanics models have signicantly

increased in numerical size. Model structurestoday typically include a few million degrees offreedom, and the largest commercial simulationsnow exceed 100 million degrees. Furthermore,when structural analyses must consider otherphysical forces such as heat transfer or uidows simulations become even larger.

As you work to solve structural problemsquickly in response to market-launch pressures,your engineering team must also support thecompanys product integrity promise. Oursoftware enables structural engineers acrossall industries to combine high speed withhigh accuracy. Two reduction techniques submodeling and substructuring enable youto condense models for rapid computation,

without signicantly aecting the accuracy ofresults. Parallel processing capabilities in ANSYSsupport the use of high-performance computing(HPC) resources. ANSYS partners with leading

hardware vendors to ensure that customers getthe coordinated expert support they need.

We also oer parametric analysis tools thatspeed up design exploration. The technologypredicts the outcome of implementing modestchanges in parameters or geometry withoutthe need to run another simulation. Design ofexperiments analyses identify the relationshipbetween performance and design variables.

With its tightly integrated technology structureand exible, easy-to-use platform, ANSYSsoftware can help you realize your productpromise condently, quickly and with a maximumreturn on your engineering investment.

The wide availability ofHPC systems is enablingimportant trends inengineering simulation.Simulation models aregetting larger usingmore computer memoryand requiring morecomputational time asengineers include greater

geometric detail andmore-realistic treatmentof physical phenomena.ANSYS tools make lightwork of these higher-delity models, whichare critical for simulationto reduce the need forexpensive physicaltesting.

Design engineers work every day with materials,components and assemblies that inherently behavein nonlinear ways. Buckling presents itself as a largedeformation, for example. Using our software to solvenonlinear problems improves the accuracy of resultsand ultimately results in better-designed products.
