The stress-strain graph provides engineers and designers a graphical measure of the strength and elasticity of a material. It allows them to predict the behavior of materials used in a given application. To draw the graph, the material must first undergo a tensile test. A tensile test is the...
empirical stress-strain curvesfunctional extremalvariational principles of mechanicsprocessing of experimental dataThe work is devoted to the formulation of mathematical models of plastic materials without hardening. A functional is proposed, the requirement of stationarity of which made it possible to ...
The stress-strain curve for an elastoplastic material with no hardening. The variableσyis the yield stress. Now, consider pure bending with a uniaxial stress state, as in a beam. As long as the material is elastic, the stress distribution is linear through the section, with the value being...
Expressions for the speed of elastic and plastic stress/strain propagation through a prestressed medium are derived. It is suggested that the speed of propagation is a function of not only the appropriate gradient of the material stress-strain curve but also of the extent of prestressing or p...
presents a more flexible and general ML framework for the prediction of deformed shapes, stress and strain fields with GNNs. Figure 1 Schematics of the proposed ML model. The meshed material or structural system is first mapped onto a graph. Three examples of various complexity are here shown....
Bones are brittle and the elastic region is small and the fracture abrupt. Eventually a large enough stress to the material will cause it to break or fracture.Hooke’s Law F = kΔL, where ΔL is the amount of deformation (the change in length, for example) produced by the force F, ...
摘要: We consider the problem of distributing the stress-strain state (SSS) characteristics in the body arbitrarily loaded on the outer surface and weakened by a physical cut with a thickness of δ0. It is assumed that δ0 parameter is the smallest possible size...关键词:...
A strain life curve modeled. The equation developed for the high-cycle straight line on the log–log strain life plot corresponds to elastic material behavior of the material. The equation developed, shown in Equation 1.20, defines two material parameters.7 (1.20)ɛe=σaE=σf′E(2Nf)b ...
Stress - strained state has been analyzed for an elastic plane subjected to the action of a travelling local surface load which is applied equally to the line on the surface and imitates loading at welding and explosion strengthening. Experimentally measured longitudinal strain on a free surface of...
Stress-strain curves are an important representation of a material's mechanical properties, from which important properties such as elastic modulus, strength, and toughness, are defined. However, generating stress-strain curves from numerical methods such as finite element method (FEM) is computationally...
