Abstract:

This is the second part of an investigation dealing with the global load-displacement behavior of a center cracked panel. Energy dissipating mechanisms of microcrack formation and macrocrack propagation are modeled separately and in combination in accordance with a predetermined criterion providing the limits for each mechanism. Nonlinear global behavior of the cracked panel is exhibited on the load-displacement curve developed by incremental loading and macrocrack growth with or without microcrack damage. jes
