“…The local geometry of each defect k is described in terms of a displacement jump in the current configuration, written as sxt, a reference configuration surface S ðkÞ s --which could be a grain boundary plane prior to intergranular fracture, for example--and a corresponding reference configuration unit normal covector, n ðkÞ s . Following Kachanov (1980), Davison (1995), Armero and Garikipati (1996), Pe z cherski (1998), and Zhou and Zhai (1999), Eq. (4) reduces to the following for the contribution to the homogenized deformation gradient due to k surface-type defects: The local deformation within undamaged regions is assumed to be describable via the multiplicative decomposition of classical crystal plasticity theory (cf.…”

“…In recent years, several versions of finite element models of Wayne State University (WSU) have been proposed (Ruan et al, 1993;Zhou et al, 1996;Al-Bsharat et al, 1999;Zhang et al, 2001). The first version dates from 1993-1997 and represents a male skull containing 32,898 knots and 41,354 elements, reaching a total mass of 4.3 kilograms.…”

Head injuries are a major health and socio-economic problem. To better protect the head against various crash, sport, or fall events, the underlying mechanisms and tolerances need to be investigated. Many investigations have been conducted using cadaver heads, animal heads, physical head models, and in vitro models throughout the world. These experiments, together with the development of computational techniques, have subsequently led to the development of numerical head models, especially finite element (FE) models, to allow more in-depth biomechanical studies. A large number of FE head models have been developed during the years and authors are trying to find the best solutions for a correct explanation of the lesional mechanisms. The finite element method (FEM) is based on the energy formulation of the mechanics of the structures and on approximation methods. It consists of approximating the actual structure through a model consisting of finite elements interconnected in points called nodes. By nodes, each item is under compatibility and balance conditions with adjacent elements. The present paper is a literature review, underlying some of the finite element models, which allowed a good explanation of the head trauma mechanisms.
