Analysis of the Elastoplastic Response in the Torsion Test

This work presents an experimental and numerical analysis of the mechanical behavior of a fixed-end SAE 1045 steel cylindrical specimen during the torsion test. To this end, an iterative numerical-experimental methodology is firstly proposed to assess the material response in the tensile test using Characterization of the strain-ratedependent mechanical Feb 16, 2021 · Cellcell junctions are essential components in multicellular structures and often experience strains of different magnitudes and rates. However, their mechanical behavior is currently underexplored due to the lack of techniques to quantitatively characterize junctional stressstrain relationships. We developed a polymeric microstructure to strain the mutual junction of a single cell

Characterization of wave propagation in elastic and

A simple model is developed to predict the peak force and wave velocity for any loading duration and amplitude. In elastoplastic chains, wave trains form even for short loading times due to a mechanism distinct from that in elastic chains. A model based on energy balance predicts the decay rate and transition point between the two decay regimes. Eects of mechanical properties and surface friction on Indentation hardness has been used extensively for material characterization and many recent computational studies have established quantitative relationships between elasto-plastic mechanical properties and the response in instrumented indentation. In contrast, very few studies have systematically quantied the eect of the plastic Elastoplastic Analysis of Mechanical Response of Buried Apr 04, 2017 · According to the plastic flow theory, the axial, radial, and hoop plastic strains were derived, and the stressstrain relation was established under the plane stress state. The axial stress and strain of the pipeline induced by fault displacements were analyzed based on the elastoplastic beam theory. Additionally, the axial stresses, hoop stresses, and strains induced by the service loads (i.e., the
