Coupled Hydro Mechanical Landslide Modeling
The video shows the results of meshfree simulation of the isometric contraction process of human medial gastrocnemius (MG) in the lower leg, where the color code represents the normal stress along the muscle. The model is constructed using MRI (magnetic resonance imaging) images, from which the geometry of MG is segmented and the pixel points are directly used as meshfree nodes in simulation. An anisotropic hyperelastic model is used to represent the muscle material and DTI (diffusion tensor imaging) images are used to provide the muscle fiber directions for the material model. Two ends of the MG are fixed to perform isometric contraction.
