The research on rate dependent material models and the material models available in commercially available finite element analysis software have been reviewed. Test data collection at various...

... data and the actual slope at t = 0 . The mismatch between the slopes results in as much as 50% errors in estimates of diffusion coefficients. Using the 3D solution in nondimensional form, the magnitudes of these errors are studied. A least-square curve-fit method, which yields accurate anisotropic...
