New Stress Formulation in X-FEM Based on Numerical Integration of Restoring Forces Using Equivalent Polynomial Functions
In this study, stress formulas in the extended finite element method are investigated. The stress components for the enriched DOFs are developed and conventional stress components of the standard DOFs are modified. The modified stresses for the standard DOFs have a unique value for the whole domain...
