Traditional analysis methods treat composite lamina as a homogenous material with uniform properties throughout. This not only masks the distinct behavior of the fiber and resin constituents, but can also lead to an inaccurate estimate of the material behavior. Accurate composite simulation requires a multiscale approach. Autodesk Helius PFA employs Multicontinuum Technology – a unique method that determines stresses and strains for the composite’s fiber and matrix. In doing so, it provides improved accuracy for determining damage initiation and predicting damage propagation. The following paper will describe the unique process used by the software to characterize the constituent properties.
