What is Introduction to Nonlinear Analysis in ANSYS about?
1) A nonlinear analysis is needed when structural stiffness changes significantly due to large strains, deflections, or contact between bodies. 2) The Newton-Raphson algorithm is used to solve the nonlinear problem by applying loads gradually in increments and performing equilibrium iterations within each increment. 3) A nonlinear analysis involves load steps to apply loads/BCs and substeps within each load step to apply the load gradually, with equilibrium iterations performed at each substep to achiev
