A note on the smoothness of energy-minimizing incompressible deformations
نویسنده
چکیده
In this note we prove that any W 1,2 mapping u in the plane that minimizes an appropriate quasiconvex energy functional subject to the Jacobian constraint det∇u = 1 a.e., are necessarily Lipschitz. Furthermore we show that the minimizers corresponding to uniformly convex energy are affine and give an example of non-affine minimizers subject to affine boundary data corresponding to a convex energy. We also discuss the regularity issues in dimension greater than or equal to 3.

A Modification on Applied Element Method for Linear Analysis of Structures in the Range of Small and Large Deformations Based on Energy Concept
In this paper, the formulation of a modified applied element method for linear analysis of structures in the range of small and large deformations is expressed. To calculate deformations in the structure, the minimum total potential energy principle is used. This method estimates the linear behavior of the structure in the range of small and large deformations, with a very good accuracy and low...
متن کاملA fiber-reinforced Transversely Isotropic Constitutive Model for Liver Tissue
Biomechanical properties of soft tissue, such as liver, are important in modeling computer aided surgical procedures. Experimental evidences show that liver tissue is transversely isotropic. In this article, considering the liver tissue as an incompressible fiber-reinforced composite with one family of fibers, an exponential strain energy function (SEF) is proposed. The proposed SEF is based on...

متن کاملمطالعه پایداری ساختاری فازهای fcc-CHX در چارچوب نظریه تابعی چگالی
Recently, a new carbon modification, namly n-diamond, have been reported, whose structure is still a matter of debate. It is important to note that the synthesis of n-diamond was carried out in the presence of hydrogen or methan. In this work we evaluate the structural stability of five fcc-CHx phases by means of first-principle calculation. The total energy is obtained as a function of the is...
