Analysis with LUSAS HPM

A coupled thermal-mechanical analysis is carried out in LUSAS to model thermal curing and calculation of residual stress. The temperature and degree of cure throughout the manufacturing process caused by the internal heat generation during cure is calculated using a transient thermal analysis. This data is then passed to a transient nonlinear stress analysis to compute the deformations due to temperature change and chemical shrinkage. Results are viewed in LUSAS HPM where displacements from the stress analysis can be factored to provide updated tool geometry. The revised tooling geometry calculated by the LUSAS HPM software can be exported in IGES format for use directly in the CNC tool cutting environment and will, in turn, produce a part that will cure into the correct shape for intended assembly purposes.

Third-party interfaces

Linking of LUSAS HPM with CATIA Composites Design is possible via Simulaytís Composites Link product.

Benefits in using LUSAS HPM

By using LUSAS HPM software in the design process competent design engineers can now extract master model and tooling surfaces "right first time" ensuring that correctly sized post-cure components are obtained without iterative guesswork. As a result the product development cycle is significantly improved. With the use of accurately calculated master and tooling surfaces it is anticipated that the cost and time required to assemble composite components could be greatly reduced. The ability to build composite components accurately will also enable larger components to be manufactured, reducing the part count and provide further savings in manufacturing costs.
