Minimizing mold deflection is essential when manufacturing plastic parts to tight tolerances. Both the mold and the machine are compliant and deform upon loading, which can affect the part quality. Therefore, understanding mold deflection during inje

Three-dimensional nonlinear finite element problems are generally very time consuming to solve accurately. A modified version of the Finite quasi-prism (FQP) element is an accurate and efficient alternative to conventional nonlinear elastic-plastic f

An important step in any finite element analysis is to determine the accuracy of the model used. For linear elastic analyses, accuracy can be measured by the convergence of the solution. Typically error norms based on the strain energy of the system
