PlySim Ltd. (Edinburgh, Scotland) has released FEMPLY Pro, a composite ply-based modelling software plug-in for Siemens’ FEMAP Pre and Post Processor. Fully integrated into FEMAP, and making use of FEMAP’s Global Ply capabilities, FEMPLY enables tabular definition of whole component laminate schedules, closely following manufacturing processes within what is said to be a simple, intuitive user interface. Multiple plies may be edited in one operation and may be re-mapped onto a new mesh or after mesh refinement. The release of FEMPLY Pro augments the FEMPLY product range adding:
- Ply draping to account for fiber angle deviation during the manufacture process and verify planned production processes, reducing the need for modifications or redesign late in the manufacturing process.
- Flat pattern export, enabling the user to directly extract 2-D CAD ply shapes for use in ply booklets or cutting patterns, enhancing the accuracy and reproducibility of the component.
- Post-processing to Hill, Hoffman, Tsai-Wu, Max Stress, Max Strain, Puck and LaRC02 failure theorems with output vectors by Layer, Global Ply and Maximum. FEMPLY Pro also offers Critical Ply and Fibre Angle output vectors to quickly and easily identify critical areas.
