[Case Study] Shape Optimization of Spot Welded Flat Plate Stiffeners ★ Detailed Materials Available

Shape optimization of quadrilateral shell elements! It is also possible to optimize the thickness simultaneously!

As an example of shape optimization analysis for shell elements, we will focus on the reinforcing material of a square plate assumed to be the "center pillar" that constitutes the body of a car. "OPTISHAPE-TS" has a function that maintains the cross-sectional shape, allowing for the avoidance of complex cross-sectional shapes of the member during the shape optimization process. In the shape optimization process, RBE3 elements and their surrounding elements are automatically treated as spot welds, and constraints are set so that only rigid body motion is possible in those areas. In other words, while the position of the spot welds may move, the size and shape of the welds are constrained to remain unchanged.
