A semi-analytical integration scheme is described in this paper which is designed to reduce the errors incurred when integrals with singular integrands are evaluated numerically. This new scheme can be applied to linear triangular elements for use in steady-state elastodynamic BEM problems and is pa
Isoparametric elements are only valid if the Jacobian determinant of the transformation between a given element and a master element does not change sign within or on the element boundary. Some algorithms are known which analyse Jacobians for various element types. Some necessary conditions are pres
## Abstract We study the accuracy and reliability of the lowestβorder bilinear shell finite element schemes. Our approach is based mainly on a simplified shallow shell model analogous to the ReissnerβMindlin model of plate bending. The numerical models are constructed by modifying the strain expres
