In this section, we discuss the role of numerical simulations in studying the response of materials and structures to large deformation or shock loading. The methods we consider here are based on solving discrete approximations to the continuum equations of mass, momentum, and energy balance.

Modeling large deformable mirrors
SPIE Proceedings, 2008Planned Extremely Large Telescopes will rely oil availability of large Deformable Mirror in the 2-3m class. Design and construction of such mirrors are challenging and call for powerful simulation tools. We present an evaluation model which is used to study performance of a large deformable mirror for three: actuator topologies. Back sensors topologies

Reconstructive elasticity imaging for large deformations
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1999A method is presented to reconstruct the elastic modulus of soft tissue based on ultrasonic displacement and strain images for comparatively large deformations. If the average deformation is too large to be described with a linear elastic model, nonlinear displacement-strain relations must be used and the mechanical equilibrium equations must include ...

Incompressibility and Large Deformations
2017We present a new point of view on the motion of an incompressible solid with large deformations. The description of the shape changes of the solid involves the stretch matrix \(\mathbf {W}\) of the classical polar decomposition. The incompressibility condition is \(\det \mathbf {W}\,\ge \,1\), accounting for possible cavitation or phase change.

Foundations of Large Deformations
1984In these lecture notes we will recapitulate some basic facts from the mechanics of a continuous medium at finite deformations, which are needed for the development of thermomechanical constitutive theory, presented in separate articles of this course on thermoplasticity.

Large Deformations of Polymers
2014The stress-strain behavior of polymers is described. The rheological equations of state for isotropic elastic materials are discussed as well as the equation of state for the ideal rubber. The theory of rubber elasticity is shortly presented.

LARGE ELASTO-PLASTIC DEFORMATIONS
2016INTRODUCTION Many materials of practical importance, such as metals, do not behave in a hyperelastic manner at high levels of stress. This lack of elasticity is manifested by the fact that when the material is freed from stress it fails to return to the initial undeformed configuration, and instead permanent deformations are observed.
