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). [[Image(Gmsh1_1.JPG,120px)]] Fig. 1 The maximum stress criterion is used for both matrix and fiber. There are different built-in failure criteria in SwiftComp which can be found in the SwiftComp user manual. In addition, advanced users can also code user-defined failure criterion with the SwiftComp executable file. In this example, the fiber is usually assumed to fail only in the fiber direction and the transverse strength constants of the fiber is usually not available. Moreover, the failure in the transverse direction of the composite is dominated by the matrix. Therefore, fictitious fiber strength constants in the transverse directions are used to ensure the failure only occurs in the fiber direction. Provide a detailed description of the problem.
