Transient Heat Conduction Problem Using Constant Strain Triangle

2 Transient Heat Conduction Problem Using Constant Strain Triangle [Pg.474]

Following the procedure used with the one-dimensional FEM model and using the constant strain triangle element developed in the previous section, we can now formulate the finite element equations for a transient conduction problem with internal heat generation rate per unit volume of Q. The governing equation is given by [Pg.474]

If we use an implicit finite difference time stepping procedure, we must evaluate the spatial derivatives in the next time step j +1. In order to arrive at a linear set of algebraic equations that can be solved using standard matrix routines, we would the like the final set of equation to be of the form [Pg.474]

The element force vector (fe) is formed by the internal heat generation term and the temperatures in the previous time steps as [Pg.474]
