MSC Software Corporation

Design Manufacturing SpA (DEMA) is a major tier-one aerospace supplier to Bombardier, Alenia Aermacchi, AgustaWestland and other leading aerospace original equipment manufacturers. The company recently faced a challenge with an aluminum acoustic barrier which is part of a jet engine nacelle. DEMA performed finite element analysis (FEA) with the MSC Nastran implicit nonlinear solver which identified two problems in the initial design. These included a stress concentration around a radius and excess material beyond the dimensions of the finished part which would have required an expensive secondary operation.

• Maintaining allowable stress concentrations during metal stamping procedure
• Reducing expensive secondary operations

• Reduced prototyping and manufacturing costs
• Substantial reductions in design time
