Providing the fundamentals of nonlinear mechanics of continuous media. Explaining kinematics and dynamics of continuum in the case of finite deformation, general principles of continuum mechanics and the basic postulates of constitutive relationship theory.
A proper understanding and working knowledge of the matter required for developing theoretical and computational models used in the analysis of deformable bodies in domain of geometric and/or physical non-linearity.
