The report describes, in some detail, a proposed computer program for the dynamic analysis of elasto-plastic, thin, isotropic plates of rectangular planform. Specific dynamic loading is considered which is appropriate to a blastwave, namely, a spatially constant pressure with infinitesimal rise time, decaying rapidly to a suction peak and finally to ambient conditions. Account is taken of the large deformations of the plate, and fixed or simply-supported boundary conditions. Much of the program has been coded and step-by-step testing of the various subroutines is currently progressing. A flow chart of the main program is given as is a statement of the subroutine testing completed as at the publication date.
