Aug 11, 2020 · This property is named as viscoelasticity. Generally, viscous substances such as water resist shear flow and strain linearly with time when we apply stress. On the other hand, elastic substances, when stretched, return to their original state once the stress is removed. Therefore, we can observe that viscoelastic materials have both these properties.
Fractional derivative in the elastic-viscoplastic stress An anisotropic elastic-viscoplastic constitutive model is developed for K-0-consolidated soft clays in general stress space. Two surfaces are assumed to exist for any loading stress as the loading
Oct 15, 2020 · We believe that the application of the workflow described here in the context of viscoplastic stress relaxation can facilitate the understanding of layertolayer stress variations with lithology and thus contribute to improved HF effectiveness.
Viscoelastic and viscoplastic stress analysis of adhesive The viscoelastic and viscoplatic effects in an adhesively bonded joint are very important to understand. Most of the adhesives used in structural applications exhibit some viscoelastic-viscoplastic behaviour, especially at high temperatures and high stress levels. The redistribution of stresses and strains that occur in joints during the viscoelastic-viscoplastic deformation influences the strength of the joints considerably.
Viscoplastic water entry Journal of Fluid Mechanics In the present study, we investigate the water entry of a viscoplastic (also known as yield stress) object. Such a material, if not sufficiently stressed, behaves like an elastic solid, but once the stress exceeds a critical value (the yield stress), the material deforms like a viscous fluid (typically with a
The archetypal feature of a viscoplastic fluid is its yield stress:If the material is not sufficiently stressed, it behaves like a solid, but once the yield stress is exceeded, the material flows
Yielding to Stress:Recent Developments in Viscoplastic The archetypal feature of a viscoplastic fluid is its yield stress:If the material is not sufficiently stressed, it behaves like a solid, but once the yield stress is exceeded, the material flows like a fluid.Viscoplasticity - an overview ScienceDirect TopicsViscoplasticity refers to the mechanical response of solids involving time-dependent, irreversible (inelastic) strains. The deformation of essentially all metals is, to a certain extent, time-dependent. This dependence, however, becomes more pronounced at temperatures exceeding
