The Karagozian & Case (K&C) cementitious material model, namely, MAT_Concrete_Damage_Rel3 (Mat_72R3), is implemented into finite element package LS-DYNA for UHPC.
Two hyper-elastic material models were considered, namely the Mooney-Rivlin model and the Neo-Hookean model.
Three methods for determination of fatigue material constants occurring in the MCB and RO models, namely, the conventional, numerical and 3D methods, were used.
This leads to a conceptual material data model consisting of three partial models, namely 'substance'phaseasystem'em', and 'phase system mathematical model', each representing a separate perspective of material data in accordance with the physical basis as well as practical uses.
Effective material properties of the FGM are estimated according to two micromechanical models, namely, Voigt's rule of mixture (ROM) and Mori Tanaka (MT) scheme.
In the context of finite element (FE) method, an efficient, accurate and general sensitivity analysis approach, namely the direct differentiation method (DDM), has been developed and extended to various element and material models.
Many models are not material models.
which combines two regularizing models, namely ROF and isotropic diffusion.
Two surface diffusion models, namely, Fick's law and HIO.
Three material models were applied.
