Finite strain theory print that page

In continuum mechanics , the finite strain theory also called large strain theory , or large deformation theory , deals with deformations in which both rotations and strains are arbitrarily large, i.e. invalidate the assumptions inherent in infinitesimal strain theory . In this case, | 2011/2/1 8:25:43

Interval finite element print that page


The interval finite element method (interval FEM) is a finite element method that uses interval parameters. Interval FEM can be applied in situations where it is not possible to get reliable probabilistic characteristics of the structure. This is important in concrete structures, wood structures

Strain energy density function print that page

A strain energy density function or stored energy density function is a scalar valued function that relates the strain energy density of a material to the deformation gradient . where is the (two-point) deformation gradient tensor , is the right Cauchy-Green deformation tensor | 2010/9/25 14:09:21

Patch test (finite elements) print that page

The patch test in the finite element method is a simple indicator of the quality of a finite element, developed by Bruce Irons . The patch test uses a partial differential equation on a domain consisting from several elements set up so that the exact solution is known. Typically, in mechanics | 2010/9/25 8:19:55

VisualFEA print that page

VisualFEA is a full-fledged finite element analysis program with many easy-to-use but powerful features, which can be classified largely into four parts: finite element processing, pre-processing, post-processing and educational simulation. All the functions are integrated into a single executable | 2011/9/4 2:57:48

Finite element method in structural mechanics print that page


The Finite element method (FEM) is a powerful technique originally developed for numerical solution of complex problems in structural mechanics , and it remains the method of choice for complex systems. In the FEM, the structural system is modeled by a set of appropriate finite elements

Infinitesimal strain theory print that page

In continuum mechanics , the infinitesimal strain theory , sometimes called small deformation theory , small displacement theory , or small displacement-gradient theory , deals with infinitesimal deformations of a continuum body . For an infinitesimal deformation the displacements and the | 2011/4/25 5:06:26
