Contact Analysis
Linear & Non linear Static Analysis
Linear contact (glued), frictional, fric-
tionless, offset etc.
Various type of contacts (ie; rigid to
deformable, surface to surface, sur-
face to edge etc)
Gasket analysis
Examples shown in the figure are
gears meshing used in rack and pin-
ion system. Frictional contact were
considered between the gears. Cylin-
drical boundary condition was used
to model gear rotation, with fixed
radial and axial direction. Also pivot
joint for a construction tying applica-
tion.
Material non-linearity (bilinear strain-
stress behaviour, hardening, etc.)
Elastic to plastic material transfor-
mation
Geometric non-linear buckling or
material failure
Large displacements or rotations
Non-linear boundary conditions
Example shown in the picture is a
drive carriage parts for a 5 tonne
capacity lift. The FEA was vital part
of the design where it enhances the
structural integrity of the compo-
nents due to its extreme loading
conditions.

Oil & Gas Offshore bleed ring
Problem
Verification of the structural integrity of a non-standard
bleed ring for oil rig application. The task is to provide
mechanical design calculation to confirm the adequacy
of the thickness of body, bolt load and gasket operat-
ing performance. Analysis should ensure that the bleed
ring can withstand the subjected assembly load and
vibration during normal operating condition.
Analysis
Taking asymmetric advantage only half of the adapter
is modelled. Bolts pretension on the adapter body is in
accordance with the API Recommended Torques for
flange. Bolts pretension on the nipoflanges is derived
from requirement in B16.5. The analysis has consid-
ered two time steps; 1. bolts pretension and 2. applied
internal pressure of up to 5000psi.
The stresses were compared to those allowed for the
material used and assessed against industry standard.
Outcome
EDSIL analysis showed that the the proposed body
thickness is sufficient to withstand the combination of
bolts pretension and internal pressure and working
within its strength capacity.

Marina Bay Sands, Singapore - Mobile Cladding
Access Platforms:
We were asked to provide design for cladding access
platforms for what is now the worlds most expensive
hotel, Marina Bay Sands. One of which was a mobile
suspended platform for to provide access to the under-
side of the Sky Park 200m above ground level. The
platforms had to run on two tracks embedded in the
structural steelwork and the platform had to be fullyclad which meant wind loading would be a major factor
in the design.
The platform was modelled using beam analysis.
Loads combinations including high wind loading were
considered according to national standard. The plat-
form was made of aluminium profile, and therefore
BS8118 was used as a verification method.
Also, a bespoke mobile trolley was design for the sus-
pended structure. As this is a one of the critical item in
the system, the trolley design was also verified by
FEA.

Problem
To verify the structural integrity of a sheet metal board in accordance
with BS EN12811-2. The actual boards of 1.5, 2, and 2.5m length
were supplied to us for in-house testing and verification.
Testing & Analysis
EDSIL has conducted a series of in-house testing as required by the
code. Comparing with initial hand calculations, the boards failed
against the initial design concept of a locked seam. Having to reas-
sess the design as behaving with a far more complex geometry has
been difficult. We have then conducted a shell finite element analysis
and ignoring the locked seam effect.
Outcome
We have finally been able to analyse the section in a manner that
allows the seam to slip. This has drastically reduced the theoretical
board capacity to a point below the tested results. With the test re-
sults now being moderately above the theoretical design capacity the
tests can now be viewed as proving the capacity of the design. This
is a requirement for passing these boards as certifiable to BS EN12811-3 and giving them a partial designation in accordance with BS
EN 12810-1 clause 5.
