IMPROVEMENT OF SHELL ELEMENTS

Introduction Often the most accurate representation of a part is through the use of shell elements.  These elements best represent parts that are relatively thin compared to their overall surface area and typically have a uniform thickness.  Shell elements have no physical thickness representation, they are displayed…

Introduction In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners.

Introduction: One of the most important techniques in CAE industry to reduce run time of an explicit analysis in FEA is “Mass Scaling” Main objective of this paper is to use mass scaling techniques to reduce the simulation run time and to ensure the stability of the simulation with mass scaling. With a mass…
