Challenge:

Designing lightweight CFRP structures with confidence requires access to allowables values. Allowables generation is extremely time and money consuming. Various layups, coupon tests and environment conditions must be covered for each characterized material system. Each test configuration must be repeated many times to obtain a statistical evaluation of the mechanical property.

Results Validation:

Digimat-VA successfully predicted allowable values within 10% error for all cases except the soft open-hole tension scenario. Typical run times for unnotched tests were 3 minutes, while it look less than 10 minutes for open-hole cases.
