Stress-Strain Analysis by the Finite Element Method
This Demonstration simulates stress-strain results in materials as derived by the finite element method. Rectangles or triangles show the segmentation of the object, where blue segments are much stronger than green segments.[more]
Red arrows show the distribution of external forces, while red points show where the object is pinned down.[less]
