What is Concept of Stress and Strain - Stress-strain Model

The yield point is the point on a stress-strain curve that indicates the limit of elastic behavior and the beginning plastic behavior.Yield strength or yield stress is the material property defined as the stress at which a material begins to deform plastically whereas yield point is the point where nonlinear (elastic + plastic) deformation What Controls Temperature Dependence of Yield Stress in The temperature dependence of yield stress and the associated dislocation dissociation in L1 2 intermetallic compounds are investigated in order to check the feasibility of the classification of L1 2 intermetallic compounds so far made in terms of the planarity of core structures of partial dislocations with b = 1/2 Temperature dependence of yield stress deformation modelt;110 Temperature dependence of yield stress deformation modegt; and 1/3 Temperature dependence of yield stress deformation modelt;112 Temperature dependence of yield stress deformation modegt; on {111} and {001} glide planes.What Controls Temperature Dependence of Yield Stress in The temperature dependence of yield stress and the associated dislocation dissociation in L1 2 intermetallic compounds are investigated in order to check the feasibility of the classification of L1 2 intermetallic compounds so far made in terms of the planarity of core structures of partial dislocations with b = 1/2 Temperature dependence of yield stress deformation modelt;110 Temperature dependence of yield stress deformation modegt; and 1/3 Temperature dependence of yield stress deformation modelt;112 Temperature dependence of yield stress deformation modegt; on {111} and {001} glide planes.

Temperature dependence of elastic and plastic deformation

Single-phase solid-solution refractory high-entropy alloys (HEAs) show remarkable mechanical properties,such as their high yield strength and substantial softening resistance at elevated temperatures.Hence,the in-depth study of the deformation behavior for body-centered cubic (BCC) refractory HEAs is a critical issue to explore the uncovered/unique deformation mechanisms.Temperature Dependence of the Yield Stress in -Titanium The effect of the activated slip systems on the temperature dependence of yield stress was investigated in -Ti by using crystal plasticity finite element method.A model for finite element analysis (FEA) was constructed based on experimental results.The displacement in FEA was applied up to the nominal strain of 4% which is the same strain as the experimental one.Temperature Dependence of the Deformation Behavior ofLarge changes in yield strength,deformation mode,strain to necking,and strain hardening capacity were seen in this irradiation experiment.The magnitudes of the changes are dependent on both irradiation temperature and neutron dose.Irradiation can more than triple the yield strength over the unirradiated value and decrease the strain to

Effects of Strain-Rate and Deformation Mode on Strain

Metastable austenitic stainless steels are prone to strain-induced martensitic transformation (SIMT) during deformation at room temperature,as in the case of sheet metal forming processes.SIMT is influenced by chemical composition,grain size,temperature,deformation mode or stress state and strain-rate effects.In this work,uniaxial and plane-strain tension tests were performed in AISI Dependence of Strain-Rate Effects on DeformationResults are reported for sixty-nine triaxial compression tests run on a marble,a lithographic limestone,a very fine-grained sandstone,and a siltstone at room temperature,dry,confining pressures of 1,000 and 2,000 bars,and at strain rates of ,,,,and /second.A decrease in strain rate from to /second at 2,000 bars confining pressure caused a decrease in strength at 2 percent strain of Deformation,yield and fracture of polymers at highthe dependence of yield stress on the hydrostatic com- ponent of stress,as well as on other variables such as temperature and strain rate (17-28).The extent to which these theories are useful for describing or predicting the pressure dependence of the shear,tensile and compres- sive yield stresses of various polymers will be discussed
