John A. Wilkinson

John A. Wilkinson, P.E.

Senior Consultant

Manager of Illinois Operations

Mr. Wilkinson has over 40 years of diverse experience in the design and analysis of structures, mechanical systems and components. His areas of expertise include design analysis, failure analysis, mechanical engineering, engineering mechanics, stress analysis, finite element analysis, fatigue analysis and fracture mechanics.

Throughout his career he has conducted hundreds of design analyses and failure investigations across a wide range of industries. Some examples include construction equipment, diesel and gasoline piston engine components, gas turbine engine components, railcars, electronic warfare systems and components, pipelines, process piping, pressure vessels, aircraft and helicopter structures and components, automotive components, ladders and aerial ladders, and steel structure collapses and crane collapses. Many of these studies were multidisciplinary in nature and often included highly nonlinear system or material behaviors.

Prior to joining ESi, he held positions with Northrop Corporation’s Defense Systems Division, Control Data Corporation’s Professional Services Division and International Harvester Corporation’s Construction Equipment Division.
