paper on 'Experimental viscoelastic Ana)ysis of Residual Stress in Therme setting Plastics' (cwuthored by Y. Miyano) on Monday, June 11 at 9:OO a.m. The first part of the presentation will provide evidence that the residual sbess h a thermosetting resin generated by d i n g is closely related to its thermoviscoelastic properties, on the basis of comparing the theoretical values calculated by the linear-visc@ elastic theory with the experlmental ones measured by the layer-removal method under various cooling con- ditkns. Next, the transient thermal stress in a strip having a circular hole which leads to the final residual stress will be analyzyzed in the case of rapid cooling at both sides by use of the photoviscoelastic method. Finally, an expedient optical method for these residualatress problems will be pro- posed and its usefulness discussed.

Professor Kunio received BS and PhD degrees in mechanical engineering

Area Attractions

Montreal is a little like Paris in North America. Although it is a French- speaking city, most people in travel- related businesses speak English. Montreal offers a diversity of shopping and nightlife that compares with that of any modern North American city.

Old Montreal, a section of the city currently being restored to the past charm of another era, is not far from the hotel. It features stone buildings, little boutiques, and lots of restaurants and outdoor cafes. Congress parti- cipants may also enjoy visiting Ouebec city, about 150 miles away from Montreal, and the Laurentian moun- tains, about an hour away.

Local Arrangements Committee

The Congress's hardworking Local Arrangements Committee (LAC) is to be congratulated for organizing the event so completely. Andrk Bazergui, Ecole Polytechnique, is the LAC chair- man. Additional LAC members include T. Bui-Quoc, Ecole Polytechnique; J. Lacoste, lntertechnology Lt6e.; G. Mclntyre, Ecole Polytechnique; J. Pro- van, McGill University; B.

Perry to Deliver Murray Lecture

C.C. Perry, Measurements Group, Inc., has been invited to deliver the 1984 William M. Murray Lecture at the V International Congress on Experi- mental Mechanics.

The Resistance Strain Gage

The subject of Dr. Perry's lecture will be 'The Resistance Strain Gage Revisited.' As the resistance strain gage approaches its 50th anniversary and continues to dominate the field of practical experimental stress analysis, Dr. Perry feels it is appropriate to re- view the characteristics of the gage with respect to current and foreseeable strain-gage measurement needs.

Dr. Perry will examine fundamental strain-gage attributes and performance criteria in terms of their effects on the accuracy of strain measurement. When feasible, given the contem- porary 'state of the art' in strain-gage technology, expected uncertainties and error magnitudes are evaluated for a range of working conditions representative of modern experimental stress analysis. He will also recom- mend remedial andlor error-limiting measures to the degree that such measures are available to the practitioner.

Authority on Stress Analysis

Known worldwide as an authority on experimental stress analysis, Dr. Perry is a senior vice-president of Measurements Group, Inc.. a sub- sidiary of Vishay Intertechnology, Inc. He is principle author of what has become a classic in its field The Strain Gage Prmer, and is the author or co- author of numerous other publications in the areas of stress analysis, fluid mechanics, statistics, tecRnical educa- tion, and the design of thermally res- ponsive bimetallic elements. He initiated and wrote SESA Newsletter, which was the predecessor to EXPERIMENTAL MECHANICS, and the R&E Technical Education Newsletter for Vishay Re- search and Education. Currently, he writes Epsilonics, a quarterly journal for stress analysts published by the Measurements Group.

Dr. Perry earned his PhD degree in

mechanical engineering at the Univer- sity of Michigan, after obtaining his MS degree in engineering mechanics and his BS degree in mechanical en- gineering at Wayne State University. He is also a graduate in automotive engineering from General Motors institute and has had training in nuclear- reactor engineering at Argonne National Laboratory.

Prior to joining Measurements Group, Dr. Perry was vice-president of En- gineering and Marketing with the W.M. Chace Company (1965-1967). Other positions he has held include: professor and Vice-chairman, En- gineering Mechanics Department, Wayne State University (1 953-1 965); Engineer-incharge of Research, Vickers, Inc. (1950-1953); and engineering posts with General Motors Central Engineering Staff and the Pontiac Motor Division.

A registered professional engineer in the states of Michigan, Ohio, In- diana, and Illinois, Dr. Perry was very active in industrial and product-liability consulting during his tenure at Wayne State University. He has been issued

C.C. Perry

over a dozen U.S. patents, as well as a number of foreign patents, and is the inventor of the 'Stress-Opticon,' a device for teaching the principles of mechanics with photoelasticity.

Dr. Perry is a long-time member, a Fellow and a Past-President of SESA, and has been named a lifetime Honorary Member and Permanent Advisor to the Southern Michigan Local Section.
