Hart-Smith Consider the Plastic Zone

In 1973, Hart-Smith took this a stage further by considering the plastic deformation of an adhesive in addition to the elastic response. This work, coupled with the finite element analysis technique provided the platform for calculation of stress distribution in complex nonlinear joints. The finite element approach to stress analysis is very convenient because the number of elements can be increased in areas of significant stress change. 

Although computing times of several hours are needed, it is possible to achieve predictions for the performance of complex assemblies. To explore these options in detail, contact the Department of Mechanical Engineering, Imperial College of Science, London.
