= John E. Crawford (engineer) =

John Edwin Crawford (born January 29th, 1943) is an American structural and civil engineer known for his many contributions to Blast Engineering, over a 50 year span, to the design of structures to resist Blast Effects and Shock. He is one of the pioneers in developing nonlinear 3-D finite element analysis techniques for predicting the actual behaviors of a broad range of structures, specializing in blast and impact effects on structures and prediction of structure failure. He is currently an owner of Karagozian & Case, Inc. located in Glendale, CA.

Career
After obtaining both his bachelor’s degree in civil engineering he went on to obtain his master’s degree in Structural Engineering and Structural Mechanics at University of California at Berkeley. In 1967, Crawford joined the Naval Civil Engineering Laboratory at Port Hueneme, CA, where he was a Research Structural Engineer. There Crawford developed a variety of finite element codes for design and study of underwater structures, airfield pavements, hardened structures, ship structures, bridges, large antennae arrays, and containerized facilities. [expand work] He went on to win Engineer of the Year at the laboratory in 1977.

In 1981, he began work at The Aerospace Corporation, in El Segundo, CA where he was an Engineering Specialist.[expand work].

In 1982, Crawford moved to TRW Defense Systems Group in Redondo Beach, CA as Senior Scientist where he performed studies of missile system vulnerability to blast and launch loads, designed space craft components, and developed software to implement various finite element capabilities needed for space craft intelligence systems. This work involved developing advanced finite element models and codes to simulate response to blast and comparing analytic results with those from companion test programs. [expand work].

It was in 1992 when Crawford joined Karagozian & Case, Inc. as a Principal Engineer and later became President and owner. [expand work]
