Evaluation of ductile fracture in sheet metal forming using a damage model
Pedro Teixeira; Abel D. Santos; J. M. A. César de Sá; Francisco M. A. PiresContinuous Damage Mechanics (CDM) may constitute an alternative to the traditional use of Forming Limit Diagrams (FLDs) to predict the onset of formability in sheet metal forming [1]. In CDM, at the constitutive level, a damage variable is introduced to model, at the macro scale, the internal material degradation due to micro-defects that occur during plastic loading. This approach is used in this work and the ...
