Prediction of the residual stiffness of the carbon fiber reinforced polymer composite, subjected to fatigue loading, can be performed using some of the phenomenological models. However, it is still a challenge to find the stiffness based on the known microstructural damage state (that was developed irrespective of the load history). In this work, t...
Non-standardization of specimen size and shape, complexities involved in specimen fabrication and its mounting on split Hopkinson pressure bar (SHPB) make it difficult to achieve reliable high strain rate mechanical properties under tensile loading experimentally. A formulation based on variable rate power law is proposed to predict the tensile str...

In the early 1980’s, the ultrasonic polar scan (UPS) technique was developed to assess the fiber direction of composites in a nondestructive way. In spite of the recognition by several researchers as being a sophisticated and promising methodology for nondestructive testing (NDT) and materials science, little advance was made during the following 3...
Composite structural parts have been successfully introduced in high performance industries. Nowadays, also lower performance, high volume production industries are looking for the application of composites in their products. Especially attractive are textile composites (woven, braided, etc.) because of their better drapability and higher resistanc...
A robust multiscale scheme referred to as micro-macro method has been developed for the prediction of localized damage in fiber reinforced composites and implemented in a finite element framework. The micro-macro method is based on the idea of partial homogenization of a structure. In this method, the microstructural details are included in a small...
