The Challenge

As part of the LCM-SMART Research & Development project led by HEXCEL, Dr. Klinkova , from the LTDS, studied the prediction of composite materials distortion and residual stresses using ESI’s simulation tool SYSPLY. 

The Benefits

- Predict the constraints and the residual stresses of a composite part
- Adapt the Finite Element model to any composite structure and
manufacturing process
- Reduce manufacturing time and cost by conducting tests on a virtual
prototype early in the development process
- Avoid distortion and delamination of the composite part

“We used SYSPLY to predict virtually the residual stresses, early in the development process. There was a good correlation between the virtual and the physical results. The use of simulation with SYSPLY was really successful.”
