Time-Swelling Superposition Principle for the Linear Viscoelastic Properties of Polyacrylamide Hydrdynamic moduli demonstrate that deswollen hydrogels exhibit the linear viscoelastic behaviors while swollen hydrogels behave as a purely elastic material. To capture the linear viscoelastic nature of deswollen hydrogels, we advocate the time-swelling superposition principle inspired by the swelling-

Application of Nonlinear Viscoelastic Material Models for the Shrinkage and Warpage Analysis of Bloare still associated with uncertainties. One of the major difficulties is the description of the complex time-, temperature- and process-dependent material behavior of semicrystalline polymers like high density polyethylene (HDPE). It is state of the art to use linear viscoelastic material models fo

Modeling Solid Materials in DEM Using the Micropolar Theory,y a set of particles representing elastic–plastic material. Recently, this method has also been used to model solid materials. In this work, we present a local constitutive model for the determination of the interaction forces, which is based on micropolar theory. The model shows an elasto-viscoplas

The Development of a Cavitation-Based Model for Creep Lifetime Prediction Using Cu-40Zn-2Pb Materiastructural mechanics and materials science is the inadequate mathematical description of creep deformation and rupture time. This situation stems not only form a lack of accurate quantification and incorporation of cavitation damage in current theoretical models, but it is compounded by the strong s

The Development and Application of Optimisation Technique for the Calibrating of Creep Cavitation Mvelop an accurate cavitation model. Most of the existing creep cavity models used some simplifications such as using average diameter of cavities, assumed nucleation, et al. Recently, the concept of calibrating the creep cavity models using 3D cavity histogram without any aforementioned simplificati
