CAEnableLtd.


Dynamic FEA:

■ Crash Analysis■ Buckling Analysis■ Metal Forming

7

CAEnableLtd.


Static FEA Example

■ Rectangular■ Flat Sheet■ Corner load■ Left edge fixed

8

CAEnableLtd.


Dynamic FEA Optimization

■ Start with a Rect. Plate (as an example)

■ Apply the expected loads & boundary conditions

9

CAEnableLtd.


Dynamic FEA Optimization

■ Sculpts it for you based on the Loads & Boundary Conditions

■ Unconventional Designs & Non-Intuitive Designs

FEA Optimized Design 1

■ Load -Fy at top right■ Left edge fixed■ Results in a different

optimal solution!

11

CAEnableLtd.



■ Load -Fy at Top Center■ Bottom edge fixed■ Same plate, different

optimal design...

12

CAEnableLtd.



■ Added load -Fx at Top Center

■ Nonintuitive design■ Optimal designs &

solutions for Multiple / Asymmetric Loads

13

FEA Optimized Design 3a

■ Not an intuitive design■ Finds solutions for

Multiple / Asymmetric Loads

FEA Optimization

■ How it works...■ Results:

Novel Design Concepts Shapes not normally

intuitive
