The paper describes a procedure for modifying finite element predictions of equivalent stress and equivalent total strain in order to obtain equivalent stress and equivalent total strain ranges for low-cycle fatigue life estimates.关键词: finite element analysis equivalent stress total strain range DOI...
It is supposed that strain energy w at a per-unit volume is a function of total equivalent strain Eeq, w=w(Eeq). Thus, total equivalent stress Σ is defined as (3.2.45)Σ=dw(Eeq)dEeq Substituting w(Eeq) into w in Eq. (3.2.34), the solutions are given by (3.2.46a)σ′=23Σ...
Noun1.equivalent weight- the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8 for oxygen combining weight,eq,equivalent atomic mass,atomic weight,relative atomic mass- (chemistry) the mass of an atom of a chemical element...
there's a dependent relation between total strain theory and equivalent hardening curve of metal plastic deformation and they may act as reason or result each other in some extent.The yield criterion may be regarded an expression of total strain theory or equivalent hardening curve in a certain ...
The measure of the scale of the turning of an object is known as angular frequency. The displacement of an object in rotational motion for period time is represented by the angular frequency. Answer and Explanation:1 Given data: Initial frequency is: {eq}{f_1} = 2\;{\rm{Hz}} {/eq}...
The equivalent total strain range is defined in accordance to the theory of von Mises and given by (2)Δεeq,i=22(1+ν∗)[(Δεxi−Δεyi)2+(Δεyi−Δεzi)2+(Δεzi−Δεxi)2+32(Δγxyi2+Δγyzi2+Δγzxi2)]0.5 ν∗ = 0,5 for plastic analysis ν∗ = 0,...
And the modulus decreases with the increase of surface roughness of the joint interface. In addition, E i is a function of E t and the thickness of joint interface h c . The cumulative plastic strain occurs with a repeated loading on the joint interface....
The rate of splitting with uniaxial strain of the fourfold degenerate (J=32) valence-band edge of silicon is computed by applying perturbation theory to the Si wave functions calculated previously by Kleinman and Phillips. Based on a "se... L Kleinman - 《Physical Review》 被引量: 307发表...
It is obvious that both the degree of physical load (e.g., given in Watts on a cycle ergometer or as speed and grade on a treadmill) as well as the amount of time spent under physical strain will consequently affect the amount of the TEA, both in its absolute value as well as its...
strain energy, it is postulated that the fracture of a representative volume element is governed by the total elastic strain energy density; that is, when the damage-equivalent stress reaches the value of the ultimate stress at fracture in tension (or compression),σuis characteristic of each ...
