... laminate is here simulated assuming each ply to be governed by the microplane model for unidirectional laminates (see Part I, ( 1 )) and calibrated in the preceding sections. At this stage, no adjustment to the model parameters is allowed, so that the numerical solution would truly be a prediction...

...Gianluca Cusatis; Alessandro Beghini; Zdeněk P. Bažant The paper presents the spectral stiffness microplane model, which is a general constitutive model for unidirectional composite laminates, able to simulate the orthotropic stiffness, prepeak nonlinearity, failure envelopes, and, in tandem...
