Our computational results reveal that fracture occurs within a “vulnerable window” inside the two-dimensional parameter space of yield strength and fracture energy and highlight the importance of taking into account the surface localization of plastic deformation to accurately predict the magnitude of ...
The tensile test is widely used for measuring the stiffness, strength and ductility of a material. The testing machine subjects the test-piece to an axial elongation and the resultant load on the specimen is measured. Depending on the nature of the product being tested, the specimen may be ro...
Thus, this definition of the yield stress, , is the single point on the stress strain curve at which the y tangent modulus, E , is changing at the greatest rate with respect to T increasing strain. The criterion for the yield stress is then !!! ! ! ! !!! ! !#$!%!!!(1a) !
The stress (R) that is determined from the intersection point "r" when the line of the linear elastic region (with slope equal to Modulus of Elasticity) is drawn from the offset "m" becomes theYield Strength by the offset method.
In this paper, an elastic-plastic tensor of the tangent modulus for plane stress problems based on Yld96 is derived, which includes the isotropic and kinematic hardening to account for the Bauschinger effect. It provides a convenient means for numerical analysis of plasticity such as the finite ...

Another way of deriving the yield stress is applying tangents to the linear viscoelastic region and the flow region, and recording intersect of these tangents as the yield stress value. Unlike the modulus-strain data, in tangent analysis the tangents are fitted to stress-strain data. Nevertheles...
