Estimation of stress intensity. For well-known crack geometries, K or G can be found from formulae or charts. For more general cases, a finite element model can be used, both to estimate K and to predict growth of a crack.Several methods can be used to make FE estimates of KI. (1) Use the stres

Orthotropic materials. Most packages accept data for orthotropic materials those for which 3 perpendicular axes the principal material axes exist. These can have 3 Young's modulii and 3 Poisson ratios. Often both directions transverse to a fibre are the same, so that we can specify just a lo

Concepts. Node - a generalised joint - connection point at which equations are written - there are at most 6 unknowns (degrees of freedom) at a node (3 displacements, 3 rotations)Element - connection between a group of nodes representing stiffness or other properties approximately- interpolation of displacement between the nodal values is used - this becomes more accurate as element size is reducedReference node - an extra point used to orient the cross-section of a beam.
