(1.1) starting from the three-dimensionaltheory of elasticity, and we relate the tension T with the elongation of the string. In additionwe derive model equations for the longitudinal displacement and the torsion of the string.The derivation of one-dimensional models from the linearized three-...
The loading speed, loading scheme (position of the supports), and the mechanical properties of the polymeric bonds are varied and their effect on the modulus of elasticity of the material is investigated. Graphical abstract 3-dimensional beams of ceramic–polymer composite materials are generated ...

One artifact of discretization when using an energy function is that the term for stretch energy will also respond to certain bend states. As a result, a simulation using such an energy function with a high stretch modulus might cause the material to looker stiffer than intended. With regular ...
