CheFEM usually uses Finite Difference Methodology (FDM) for solubility and diffusion calculations regarding multilayer / laminate materials. Large magnitude differences in layer thicknesses (micro and nano layers) and interfacial concentrations can be handled much more efficient and effective with FDM (compared to FEM). Subsequently, stresses and strains are quantified using classic laminate theory and/or FEM.
Especially if the laminate is subjected to external stresses (a mechanical load), intrinsic stresses (complex shapes, 90 and 180 degrees bends) and/or residual stresses (thermal), FEM is the best method for the "after" processing/visualization.
Is this helpful?
