Mechanical Response of Materials with Physical Defects. Part 2. Combined Modeling of Material Damage and Crack Propagation for Center Cracked Panel.

摘要

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)
