In the initial compression stage, the collapse initiation stress, σc0, is usually used to indicate the yield strength, which can be obtained as the first peak stress or the stress at which the tangent modulus is the first minimum. Although an offset yield stress (e.g. 0.3% offset yield...
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 ...
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...

When the damage reaches 0.67, the residual stress is 10.3, 9.3, and 8.6 MPa, respectively, and the corresponding values are very close the uniaxial compression strength. So considering the damage effect on the stress drop is more reasonable. By introducing the stress drop at the elastoplastic ...
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.
After yielding, abundant proliferation of SIM α″which assisted by multi-scale α phases and their interactions are the fundamental reasons for achieving higher work-hardening ability, tensile strength (1215 MPa) and uniform elongation (11%). Thus, the core strategy to realize the excellent ...
Frequency dependence of storage modulus G′ and loss modulus G″ for 1 μm silica/PDMS suspension with the particle volume fraction 10.7 vol%. The strain amplitudes at each field strength are 10% for E≤ 60 V/mm, 1% for E=100 and 250 V/mm, 0.2% for E=500, and 1000 V/mm, and ...
