1) plane of maximum shearing stress 最大剪应力面2) ultimate shear stress 最大剪应力 1. To achieve easily and rapidly the key data of the yield shear stress and ultimate shear stress,the double-hole micro-shear,transistors and microchip machine MSP430F149 are used in the testing system. ...
Maximum in-plane shear stress (5.4)τmax=(σx−σy2)2+τxy2 Orientation of the planes of maximum shear stress (5.5)tan2θs=−(σx−σy)/2τxy Equation (5.5) has two roots θs1 and θs2 see Fig. 5.2.4. On each of the planes of maximum shear stress, there acts a normal...
maximum shear stress (MSS)multsiaxial fatigueAn improved high-cycle multiaxial fatigue criterion based on the critical plane was proposed in this paper. The critical plane was defined as the plane of maximum shear stress (MSS) in the proposed multiaxial fatigue criterion, which is different from ...

A shear stress based critical plane criterion of failure, modified for the effect of normal stress in the plane of maximum range of shear stress, was used to predict fatigue lives of thin wall tubular specimens subjected to biaxial in phase and 90 deg out of phase tension torsion loading. Th...

It can be determined as a function of maximum shear stress amplitude and maximum normal stress. The critical plane is the one with highest value of damage parameter. The parameter can be expressed as: (1)FP=Δτmax2+k1σnmax The number of cycles to crack initiation can be determined as ...
Instantaneousu-υsignals in the turbulent far wake of a cylinder have been analysed using an extended “quadrant analysis” in order to investigate the Reynolds stress structure and the features of large eddies. The results indicate that the region between the location of maximum shear and the edg...
