Approximated analytical methods for evaluation notch stress and strain under multiaxial loading are considered. Results from analytical methods are compared to results from elastic-plastic finite element analysis. An engine bearing cap is evaluated under both methods, considering the services load from the combustion pressure and also the bolt tension. Linear kinematic hardening rule and Mises plasticity model have been considered. Results from analytical models and nonlinear finite element analysis are compared.
