<div>Resumen: Direct methods of Calculus of Variations are a rigorous framework to treat mathematically interesting variational problems arising in science or engineering. The methods are based on the notion of lower semicontinuity, which classically is based on the convexity of the integrad function however this assumptions is unrealistic in the framework of nonlinear elasticity.<br>
Then it must be replaced by different and more general conditions, named quasiconvexity and polyconvexity. In this conference I introduce some new recent semicontinuity results for non coercive polyconvex functionals. Moreover we present some existence results for polyconvex and also non polyconvex problems, which are related with the Odgen model for Rubberlike Materials. This existence results are strictly connected with the resolution of the Prescribed Volume Equation.<br>
