Energy Approaches to Structural Vulnerability with Application of the New Bell Stress - Strain Laws

Abstract

This report summarizes the various ways in which energy absorbed by a structure can be used in vulnerability studies. Three approaches are explained and mathematical relationships given for each. An extensive presentation is given of a simplified variational approach with applications shown for beams and plates. Finally the new Bell Stress-Strain Laws are applied to compute energy and plastic deformation in beams and plates.
