Element Matrices Institute of Structural Engineering Method of Finite Elements II 12
Element Matrices where the following notation has been used H S , H = the shape function matrices (usually denoted by N) 0 f S , 0 f B = vector of surface and body forces at time 0 B L , t 0B L , t tB L = linear strain displacement transformation matrices t 0B NL , t tB NL = nonlinear strain displacement transformation matrices 0C, t C = incremental stress strain material property matrices t τ , t ˆτ = matrix and vector of Cauchy stresses t 0S, t Ŝ = matrix and vector of 2nd Piola-Kirchhoff stresses These matrices depend on the type of Finite Element considered Institute of Structural Engineering Method of Finite Elements II 13
