In the investigated triaxiality regime an exponential dependency of the fracture locus on the stress triaxiality ratio was found.doi:10.1016/j.engfracmech.2007.03.021Gernot TrattnigThomas AntretterReinhard PippanEngineering Fracture MechanicsFracture of austenitic steel subject to a wide range of stress ...
ν is Poisson’s ratio, τxy is shear stress. Equation (1.43) is valid for complex stress states. In a plane bar under uniaxial tension σ2 = σ3 = 0, the Formula (1.43) transfers to (1.42). In a bending specimen with a notch or a precrack, multiaxial stresses are produced ahead...

It is shown for 124 Cs that one can reproduce the signature dependence of the energy and the B(M1)B(E2) ratio best when one takes into account γ-deformations with irrotational-flow moment of inertia in addition to the proton-neutron interaction proposed by Semmes and Ragnarsson. Including ...
The range 0 < 渭 < 渭 c of stability of the triangular points is reduced in the presence of any of the perturbations, except when considering the potential from the belt the range increases, where 渭 c is the critical mass ratio. The oblateness of a test particle (of infinitesimal mass)...

The energy release rates for different triaxiality ratiosS/Tfrom uniaxial tension (S/T= 0) to hydrostatic tension (S/T= 1) are determined using a finite element method (FEM). For small deformations, our results agree with linear elastic theory where the energy release rate is independent ofS...

Involving invariants of the Cauchy stress tensor σ, the stress triaxiality is the ratio of the mean normal and equivalent stresses:(1)T=σmσeqv,where(2)σm=13trσ,(3)σeqv=32σ′:σ′,σ′=σ−σmI.In uniaxial tension, the triaxiality is 1/3. Above 1/3, triaxiality increases ...
The equation for the elastic collapse pressure Pel is Pel=2E1−ν2tD3where ν and E are the material’s Poisson’s ratio and Young’s modulus, respectively. Note that only elastic material parameters come into play, which means that in these cases the instability takes place while the ...
