Expert FEM-Tools

Inventor Sim Results may be not accurate enough Large Deformation Effects

Material Properties behave Non-Linear (eq. Plastic)

Load Case cannot be captured in Inv Sim Time dependent behaviour (eq. sudden stop)

Thermal Stresses

Failure Mode is not captured Buckling

Typical Design Challenges

• Deformation of Plastic Parts?

• Cross-Plate Bending?

• How many cycles to failure?

• What are the effects of vibration?

• Will my product buckle?

• Will the parts connect together properly?
