The ductile failure of porous metallic materials is studied here using both Limit Analysis (LA) methods, a problem treated by Gurson with his famous kinematic approach in 1977. The present work is devoted to determining the strength of porous materials with long circular cylindrical cavities in the...

Steel, like many materials, can withstand higher stresses in compression before yielding than in tension. This is due to the different ways materials fail under tension (where they are pulled apart) versus compression (where they are squeezed together). Tensile Yield Strength of Steel Refers to t...
It seems to me that the ultimate strength of a brittle material can be easily determined by a bending test, but what about the yield? In the brittle regime, I can see how you couldn't, since the sample would fail before it would flow significantly. However, brittle materials can be made...

Yield strength: It is the yield limit when the metal material yields, that is, the stress that resists the slight plastic deformation. For metallic materials without obvious yield, the stress that produces 0.2% residual deformation is defined as its yield limit, which is called the conditional ...

2.Evaluation of uncertainty of measurement in testing for materials at ambient temperature has been discussed,including tensile strength;lower yield strength;proof strength,non-proportional extension;percentage elongation after fracture and percentage reduction of area.文章介绍了金属材料室温拉伸试验测量结果不确...
Ferromagnetic materials are widely used in industry and risking the hazards of aging and degradation of their mechanical properties. This paper proposed a non-destructive method for the measurement of the yield strength of ferromagnetic materials imprinted by the materials’ microstructure as the microstru...
