== Problem Description == {{{ The effective initial failure strength constants of fiber-reinforced unidirectional composites are predicted using the MSG solid model. A square packed mechanical model is used as shown in Fig. 1. The MSG solid is used to first perform homogenization analysis to get the effective properties of this composite. Then, the MSG-based initial failure analysis is carried out for computing the effective strength constants, which can be used in the upper scale models (e.g., yarn or lamina). [[BR]] Provide a detailed description of the problem. Possibly with a picture. Insert picture using [[Image(ProblemPicture.jpg)]] where the file ProblemPicture.jpg should be attached. }}} ---- == Software Used == {{{ Provide which code, which version, and also which interface are used for the solution.
