Multiaxial Fatigue Lifetime Estimation Based on New Equivalent Strain Energy Damage Model under Variable Amplitude Loading

Crystals
The largest normal stress excursion during contiguous turn time instants of the maximum torsional stress is presented as an innovative path-independent fatigue damage quantity upon the critical plane, which is further employed for characterizing fatigue ...

Multiaxial Fatigue Life Calculation Model for Engineering Components in Rolling-Sliding Contact

MATEC Web of Conferences, 2018
Number of important engineering components and elements such as gears, rollers, bearings operate in conditions of rolling-sliding contact loading. Determination of fatigue lives of such components and elements is very important for engineering practice ...

Renormalized field theory and particle density profile in driven diffusive systems with open boundaries

, 1996
We investigate the density profile in a driven diffusive system caused by a plane particle source perpendicular to the driving force. Focussing on the case of critical bulk density $\bar{c}$ we use a field theoretic renormalization group approach to ...

Stiffness dependence of critical exponents of semiflexible polymer chains situated on two-dimensional compact fractals

, 2009
We present an exact and Monte Carlo renormalization group (MCRG) study of semiflexible polymer chains on an infinite family of the plane-filling (PF) fractals. The fractals are compact, that is, their fractal dimension $d_f$ is equal to 2 for all members

On the Behaviour of 316 and 304 Stainless Steel under Multiaxial Fatigue Loading: Application of the Critical Plane Approach

Metals, 2019
In this work, the multiaxial fatigue behaviour of 316 and 304 stainless steel was studied. The study was based on the critical plane approach which is based on observations that cracks tend to nucleate and grow in specific planes.

Expansion for the solutions of the Bogomolny equations on the torus

, 2004
We show that the solutions of the Bogomolny equations for the Abelian Higgs model on a two-dimensional torus, can be expanded in powers of a quantity epsilon measuring the departure of the area from the critical area.

Contribution to fatigue damage prediction of thin shell finite element models

MATEC Web of Conferences, 2018
The paper deals with the implementation of the chosen fatigue damage criterions into FE analysis. Our study considers a shell finite element structural analysis in conjunction with the multiaxial rainflow counting and the fatigue damage prediction.

Multiaxial fatigue modeling of continuous fiber-reinforced polymers using a critical plane approach

Archives of Civil and Mechanical Engineering
Abstract This paper presents extension of the application of a damage parameter recently shown to successfully model multiaxial fatigue behavior of short fiber-reinforced composites to continuous fiber composite materials. The authors conducted an experimental campaign on the fatigue life of carbon fiber-reinforced polymer ...
