Numerical models are useful to better understand the mechanical responseof various tissues and materials. With the discrete element method, it is possible to model complex structures with simple elements: small mass elements connected with springs. The macroscopic response of the tissue can then be explained by its microscopic description. We propose to model tensile tests on fascia lata using this method, because of its structure composed of two layersof collagen fibersconnected by a proteoglycan matrix .
