In recent years, there has been a rising interest in developing computational models to predict the inelastic deformation and fracture of polymer composites. This interest is particularly noticeable in the aerospace and automotive industries, which are motivated by the need to reduce product development procedures and costs while also attempting to design and build more competitive products.
The Smeared Crack Model (SCM), developed by Camanho et al. (2013), is a complete three-dimensional model that predicts the onset and propagation of ply failure mechanisms. SCM is modified by a new plasticity prediction system based simply on shear strength and shear modulus. As a result, using SCM in conjunction with the reduced order model greatly reduces the time and expense required to collect critical material data. Furthermore, it has been observed that using the elastic-plastic SCM improves the accuracy of predicting ultimate strengths significantly when compared to using only the elastic SCM.
