Damage Evolution Prediction during 2D Scale-Model Tests of a Rubble-Mound Breakwater: A Case Study of Ericeira’s Breakwater

open access: yesModelling, 2022
Melby presents a formula to predict damage evolution in rubble-mound breakwaters whose armour layer is made of rock, based on the erosion measured in scale-model tests and the characteristics of the incident sea waves in such tests. However, this formula

Energy Evolution Law of Marble Failure Process Under Different Confining Pressures Based on Particle Discrete Element Method

open access: yesFrontiers in Materials, 2021
The energy dissipation usually occurs during rock failure, which can demonstrate the meso failure process of rock in a relatively accurate way. Based on the results of conventional triaxial compression experiments on the Jinping marble, a numerical ...

Experimental Investigation on Uniaxial Compression Mechanical Behavior and Damage Evolution of Pre-Damaged Granite after Cyclic Loading

open access: yesEnergies, 2021
Failure behavior of pillars in deep mines is affected by various cyclic loads that cause initial pre-damage. Pillars will be further damaged and developed in the long-term compressive stress until they are destroyed.

Acoustic Emission Characteristics and Damage Evolution of Rock under Different Loading Modes

open access: yesEnergies, 2020
To study the evolution of acoustic emission (AE) parameters and the differences in the fracturing and failure process of rocks under different loading modes, AE signals of marble were detected during uniaxial compression tests (UCTs), direct tensile ...

Study on the deterioration trend of the rock mass on the reservoir banks under dry-wet cycles

open access: yesFrontiers in Ecology and Evolution, 2022
The deterioration of rock mass under dynamic mechanical state is difficult to determine, especially when evolution trends of micro-fractures are considered.

Mechanical properties and damage evolution of granite under high temperature thermal shock

open access: yes工程科学学报, 2022
Hot dry rock (HDR) is an underground rock with high temperatures (usually above 180 °C), low porosity, and low permeability. The extraction of geothermal energy from HDR generally requires the stimulation of man-made reservoirs.

Damage control surgery: a constant evolution

open access: yesColombia Medica, 2020
The story of trauma resuscitation is similar to that of many other advances in medicine: described, forgotten, reinvented, ridiculed, and finally accepted. Even after acceptance, the concepts go through periods of neglect and indifference before they are tried and enhanced, till the next advance.
