Mixed Finite Element Methods and Applications

WebThe theory of elasticity is used to predict the response of a material body subject to applied forces. In the linear theory, where the displacement is small, the stress tensor which measures the internal forces is the variable of primal importance.

We discuss the application of Virtual Elements to linear plate bending problems, in the Kirchhoff–Love formulation. As we shall see, in the Virtual Element environment the treatment of the C 1 -continuity condition is much easier than for traditional Finite Elements. The main difference consists in the fact that traditional Finite ... mommy mommy mommy look at my tummy
