Firehole Technologies Inc. (Laramie, Wyo.) has announced the availability of Helius:MCT software, designed as an enhancement to commercial finite element analysis packages to improve the accuracy of composite structures modeling and simulation. Based on the company’s Multicontinuum Technology (MCT), it replaces traditional methods used for composites failure prediction (e.g., Tsai-Wu, Hashin or Hill), which treat a composite lamina as a homogeneous solid with uniform properties throughout. According to the company, this limits success in failure prediction because the constituent stress state, not the composite (that is, the homogenized) stress, drives failure. By analyzing fiber and matrix stresses separately, this software reportedly leads to more accurate composite failure predictions.
