Evaluation of Parameters used in Progressive Damage Models
PI(s): John Parmigiani, Ph.D. (Oregon State University Mechanical Engineering)
Motivation and Key Issues • The matrix-compression material-model used in Abaqus for carbon fiber laminates is computationally efficient but is physically unrealistic and does not correspond to actual material behavior. Objective • Determine the conditions under which the use of this unrealistic material model causes significant errors in predictions of carbon fiber laminate response to […]
