Firehole Composites (Laramie, Wyo.) has released Helius:MCT v5.0, its platform for finite element analysis of composite materials. The software permits accurate progressive failure analysis of composite structures. Results feature builtin, constituentbased failure criteria. Version 5.0 includes enhancements to further improve the efficiency and robustness of analyses using cohesive zone modeling to simulate delamination and disbonding. Firehole has also broadened the utility of Helius:MCT by extending the technology to additional failure criteria and opening its platform to userdefined criteria. The package now offers several failure criteria, including some recent developments by Hashin, Puck and Christensen. Other enhancements in Helius:MCT v5.0 include extended support for Linux, Abaqus 6.12 and ANSYS 14. Additional solution time efficiency is achieved with the implementation of an ultimate failure monitor. Referred to as the Job Terminator, the feature can monitor an analysis for ultimate failure and terminate the processing.
