If the mesh is fine enough to look smooth, why does the peak stress still jump every time we refine it?

Discover How Numerical Methods Solve Stress When Equations Fail — When geometries, boundaries, or loads become too irregular for closed-form solutions, engineers discretize the continuum into finite collections of points, lines, or subdomains. The Finite Element Method dominates by dividing the structure into elements whose local displacement fields are approximated with polynomials, then assembling those element matrices into a global system solved for nodal displacements and the resulting…
