On the Influence of Mean Shear Stress on Multiaxial High Cycle Fatigue of Metallic Materials [PDF]

Materials Research, 2021
A study has been made of the influence of a superimposed mean shear stress on the capability of some multiaxial high cycle fatigue criteria to predicting fatigue behavior of 42CrMo4 and 34Cr4 alloy steels.

Effective strain criterion under multimode and multiaxial loadings – A rubber S–N curve with the scatter-band factor of 1.6 from 90 fatigue cases

eXPRESS Polymer Letters, 2022
The effective strain criterion, unifying multimode and multiaxial loadings to a single parameter and being expressed in analytical form with no need to rotate a plane to search the maximum damage parameter, is proposed for the fatigue design of anti ...

Research of Fatigue Crack Growth Based on Critical Plane Method

MATEC Web of Conferences, 2016
To precisely simulate the path of crack growth, a simulation of crack growth progress has been presented by using the redevelopment function of ANSYS APDL and introducing the random criterion of crack propagate directions with critical plane approach ...

Approximation of the critical buckling factor for composite panels [PDF]

, 2012
This article is concerned with the approximation of the critical buckling factor for thin composite plates. A new method to improve the approximation of this critical factor is applied based on its behavior with respect to lamination parameters and ...

Determination of critical current density in melt-processed HTS bulks from levitation force measurements

, 1999
A simple approach to describe the levitation force measurements on melt-processed HTS bulks was developed. A couple of methods to determine the critical current density $J_c$ were introduced. The averaged $ab$-plane $J_c$ values for the field parallel to

Critical point of QCD at finite T and \mu, lattice results for physical quark masses [PDF]

, 2004
A critical point (E) is expected in QCD on the temperature (T) versus baryonic chemical potential (\mu) plane. Using a recently proposed lattice method for \mu \neq 0 we study dynamical QCD with n_f=2+1 staggered quarks of physical masses on L_t=4 ...

Fatigue life estimation in welded joints under multiaxial loadings [PDF]

Fracture and Structural Integrity, 2009
Welded joints are frequently locations for cracks initiation and propagation that may cause fatigue failure of engineering structures. Biaxial or triaxial stress-strain states are present in the vicinity of welded joints, due to local geometrical ...

Effect of anisotropy on the field induced quantum critical properties of the three dimensional s=1/2 Heisenberg model

, 2010
The field induced quantum critical properties of the three dimensional spin-1/2 anisotropic antiferromagnetic Heisenberg model has been studied. We have investigated the quantum phase transition between the spiral order and field induced ferromagnetic ...
