Mathematical framework for unsaturated flow in the finite deformation range
finite deformation finite element heterogeneity porous media unsaturated soil
2015/7/1
The presence of fluid in the pores of a solid imposes a volume constraint on the deformation of the solid. Finite changes in the pore volume alter the degree of saturation of a porous material, impact...
Discrete micromechanics of elastoplastic crystals in the finite deformation range
Crystal plasticity Finite deformation Micromechanics Stress-point integration Strong discontinuity
2015/7/1
We present a rate-independent crystal plasticity theory in the finite deformation range. The formulation revolves around theory of distribution and strong discontinuity concepts applied to the slip sy...
Finite deformation formulation for embedded frictional crack with the extended finite element method
finite deformation frictional crack embedded discontinuity extended finite element
2015/7/1
We reformulate an extended finite element (FE) framework for embedded frictional cracks in elastoplastic solids to accommodate finite deformation, including finite stretching and rotation. For the FE ...
A Three-dimensional Viscoelastic Constitutive Model of Finite Deformation
viscoelastic finite deformation the principle of objectivity
2012/9/24
Hereditary integral formulations and differential formulations identified with spring and dashpot constructions can express the viscoelastic behaviors of polymeric materials at small deformations. In...
