Plastic intermittency during cyclic loading: From dislocation patterning to microcrack initiation [PDF]

Physical Review Materials, 2019
In metallic materials subjected to cyclic loading, strain hardening as well as fatigue crack initiation have been linked for a long time with the evolution of dislocation patterns and structures. In particular, the development of low-energy dislocation configurations such as persistent slip bands (PSBs) is considered as a precursor to crack initiation.

Analysis of the asynchronous electrical drives for the industrial machines with a cyclic (intermittent) electrical shock load

Bakar, 2023
The analysis and proposed optimization technique of asynchronous electric drives of production machines with a cyclic impact load, under the condition of minimum energy consumption, was presented in this paper. The mean values of the electric motor torque in the working range of a slider, were adopted in calculation. The derived formulae can be used to

Experimental study on equilibrium initiation and extension of multiple clusters of fractures based on true triaxial physical simulation

Journal of Natural Gas Geoscience, 2023
In the context of tight sandstone reservoirs in the Ordos Basin characterized by compact and heterogeneous rock formations, conventional fracturing techniques yield monolithic fracture shapes, rendering 3D reservoir reconstruction unattainable.

The Distinct Elemental Analysis of the Microstructural Evolution of a Methane Hydrate Specimen under Cyclic Loading Conditions [PDF]

, 2019
Submarine slope instability may be triggered by earthquakes and tsunamis. Methane hydrate sediments (MHS) are commonly buried under submarine slopes. Submarine slides would probably be triggered once the MHS are damaged under cyclic loading conditions ...

Experimental study on coupling effects of cyclic confining pressure and intermittent cyclic loading on deformation behavior of saturated soft clay

Yantu gongcheng xuebao
The deformation characteristics of soft clay under intermittent cyclic loading and cyclic confining pressure are studied by conducting two types of cyclic triaxial tests, i.e., continuous cyclic loading and intermittent cyclic loading triaxial tests, and
