STRENGTH PREDICTION SYSTEM AND METHOD FOR COMPOSITE LAMINATES

摘要

A method of predicting the strength characteristics of a composite laminate (100) may include loading a structural model (115) of a composite laminate (100) formed of a material system. The method may additionally include comparing strain invariants from loading the composite laminate (100) to critical strain invariant values of the material system. The method may also include identifying, as a first significant event (FSE), a strain invariant of the matrix (104) and/or the fibers (106) reaching a critical strain invariant value.
