Abstract

SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.

Abstract

This chapter deals with the nonlinear dynamic responses of structures with flat mid-surfaces, such as plates and boxes by employing the mixed formulation based three-node flat triangular nonlinear shell elements presented in Chapter 7. Geometrical nonlinearity due to large deformation, material nonlinearity due to elastic-plastic material behaviour, and various loading situation including non-conservative loads, will be investigated.

Keywords:

Dynamics, nonlinearities, geometrical, material, flat-surface.
