Multiaxial low cycle fatigue behavior of notched components under non proportional loading

multiaxial low cycle fatigue for smooth specimens, a limited number of papers have been reported for notched specimens [11,12]. The number of papers available in literature decreases even more when low cycle fatigue under non proportional loading is

The objective of this work is to investigate the use of metallurgical gradients (MG) in the design of structural components made of ductile cast iron (DCI). MG have been realized in this study by locally varying the pearlite fraction of the matrix. Exemplarily, the allowable cyclic load for a drive shaft as well as the allowable static displacement are calculated. The performed calculations

Prediction of failure in notched carbon

Three-dimensional FE simulations of the progressive damage and failure of centre-notched quasi-isotropic CFRP laminate specimens under multi-axial loading were performed using the explicit version of the commercial FE package Abaqus FEA (v. 6.12). The.

Stress and Strain Analysis of Notched Bodies Subject to

Abstract—In this paper, an analytical simplified method for calculating elasto-plastic stresses strains of notched bodies subject to non-proportional loading paths is discussed. The method was based on the Neuber notch correction, which relates the incremental elastic and elastic-plastic strain energy densities at the notch root and the material constitutive relationship. The validity of the

Deviatoric Neuber method for stress and strain analysis at

This is based on the fact that the original Neuber Rule was developed for notched elements under pure shear loading conditions, but it has been extended to other multiaxial loadings where the current stress state can be different from the pure shear stress state.

This thesis presents experimental and numerical investigations on the fracture properties of quasi-brittle materials, including mortar, concrete and graphite. Fracture toughness in terms of the critical stress intensity factor K_IC and fracture energy G_F of the materials were determined through three-point bending tests on centre-notched beams. Furthermore, full-field displacement of the

Influence of Notch Sensitivity and Crack Initiation Site on

A series of strain-controlled multiaxial low cycle fatigue (LCF) tests under proportional and non-proportional loading conditions have been conducted on notched specimens. Cylindrical bars of Al 6061 aluminum alloy and AISI 316L stainless steel with four values of stress concentration factors referred to the net section K t,n were employed.
