Abstract:

The existing PETROS 4 finite deflection elastoplastic structural shell response code was modified to permit analysis of the response of structural panels to nearby high explosive detonations. A modified constitutive formulation involving prescribed through-thickness stresses was introduced. Previously omitted surface traction terms were added to the equations of motion. A recycling option based on a strain equivalence criterion was introduced to inhibit the unrestricted growth of a breathing mode. Additional printer and plotter output features were incorporated into the program.
