Abstract

There are numerous applications, of technological interest, where materials of quasi‐brittle behavior, as in the case of cement‐based composite materials, rocks and composites formed by the mixture of ceramics with other phases, are subjected to oscillating loads and suffer [...]

Abstract

This paper discusses tidal, ocean, and river free turbine functional design parameters and general considerations associated with tidal field developments. A particular focus is on the importance of considering mechanical fatigue and the associated calculation method when designing [...]

Abstract

We develop a phenomenological model of electro-mechanical ferroelectric fatigue based on a ferroelectric cohesive law that couples mechanical displacement and electric-potential discontinuity [...]

Abstract

In this paper, we seek to minimize the cost of the anchoring system of a floating offshore wind turbine under reliability constraints. Taking into account the uncertainties on the model, on the resistance threshold and on the environmental conditions implies constraints expressed [...]

Abstract

The energy-based fatigue model presented in this work overcomes different shortcomings of existing model approaches, such as the need of separated assumptions for constant life diagrams. By using the range of the normalised strain energy density and a probabilistic based mode interaction [...]

Abstract

This work is a brief report about the problem of life -or, durability study- of structural materials, undergoing mechanical, thermal and chemical actions. This document is approached from [...]

Abstract

International audience; The safety of gas transportation pipelines under fatigue loading remains an important issue. The purpose of the present study is to better evaluate the fatigue crack growth (FCG) behavior by carrying out analysis/predictions and experiments in full-size pipeline [...]

Abstract

Glass fibers were used to investigate the impact of loose fiber reinforcement on the performance characteristics of"br" asphalt mixtures. For the laboratory tests on asphalt mixes a fiber content of 0.5 mass.-% was chosen. This paper"br" presents selected results of fatigue, stiffness [...]
