The von Mises Criterion (1913), also known as the maximum distortion energy criterion, octahedral shear stress theory, or Maxwell-Huber-Hencky-von Mises theory, is often used to estimate the yield of ductile materials. The von Mises criterion states that failure occurs when the energy of disto...

Failure theory is the science of predicting the conditions under which solid materials lose their strength under the action of external loads. The failure of a material is usually classified into brittle failure (fracture) or ductile failure (yield). Depending on the conditions (such as temperature...

topology optimization method (STOM) that considers various static failure criteria, including those from the maximum shear stress theory, the distortion energy theory, the ductile Coulomb–Mohr theory, the brittle Coulomb–Mohr theory, and the modified Mohr theory for ductile and brittle materials. Due...
They are used principally in predicting the failure of the (hard) engineering materials, but can be used or modified for many other types of material. 1. Maximum Principal Stress Theory Consider a very brittle material, such as a ceramic or glass, or cold metal. Such a material will ...
Dislocation Theory of the Fatigue of Metals "A dislocation theory of fatigue failure for annealed solid solutions is presented. On the basis of this theory, an equation giving the dependence of the n... ES Machlin - 《Technical Report Archive & Image Library》 被引量: 13发表: 1947年 Finite...
Failure modes&failure theories_Mechanics of Materials Theories of Failure Failure is generally perceived to be fracture or complete separation of a member. However, failure may also occur due to excessive deformation (elastic or inelastic) or a variety of other reasons.Failure Modes 3 Excessive ...
1. Determine the factor of safety for the following plane stress states by using the distortion-energy and maximum shear stress theories, for ductile AISI 1020 cold-drawn steel with yield strength equ For a ductile bar (S_y = 50 kpsi), using the maximum-shear stress ...
In this application to uniaxial tension and compression, and within the framework of isotropic failure theory there is always T # C. Equality occurs in the perfectly ductile case. Any apparent data that seems to suggest T C would not be admissible. Significance and Conclusions The yield stress ...
