Fracture mechanicsContinuum damage mechanicsThe damage of materials is the progressive physical process by which they break. The mechanics of damage is the study, through mechanical variables, of the mechanisms involved in this deterioration when the materials are subjected to loading. At the microscale...
A damage model and simulation method are developed to simulate fracture process of geoengineering structures by using the continuum damage mechanics. The main contribution of this study is that the principle of minimum dissipative energy is used to develop the damage model, in which each parameter ha...
Of course, these degradation mechanisms may differ from one system to another to which extent they occur. At all levels of the stacking, cracks and/or delamination between layers can occur. These phenomena are triggered by mechanical stress. Interfacial stability remains an issue, although it can...

Research limitationsThe perfect von-Mises plasticity together with Lemaitre damage model is considered within the realm of small deformations.Practical implicationsUpdating stress and plastic internal variables are of utmost importance in elastoplastic analyses of structures. The accuracy and efficiency of ...
(Zou et al.2020). Because ACE2 is, based on current knowledge, the main vector by which SARS-CoV-2 enters the body’s cells, changes in ACE2 expression should have an impact on the severity and time course of COVID-19 symptoms. Second, changes in NTS signaling may play a key role...
Semi-crystalline polymers are now extensively used in various applications such as aircrafts, civilian structures, oil and gas platforms and electronics. They are, however, inherently damage prone, and over time, the formation of damages such as cavitation and crazing causes degradation in mechanical ...
Dougill first applied damage mechanics to rock study [14], followed by Lemaitre, Chaboche, Krajcinove, Taehyo, Murakami, and Heping Xie, who studied the damage mechanics of rock by taking advantage of different definitions of damage variables, damage parameters, yield principles, and conditions. ...
The damage variable of the sandstone has a power function relation with the increase of drying-wetting cycle numbers. A traditional strength prediction model based on P-wave velocity was established combined with the damage theory and Lemaitre strain equivalence hypothesis; in view of the defects of...
