Abstract
This study aims to investigate the mechanical properties and damage constitutive model of marble under cyclic loading‐unloading conditions. Triaxial cyclic loading‐unloading tests were conducted to examine the effects of confining pressure on the strength, deformation, and damage evolution of marble. The experimental results demonstrate that confining pressure significantly influences the mechanical behavior of marble, particularly at high confining pressures, where marble exhibits enhanced plastic deformation capacity and higher strength. As the confining pressure increased from 5 to 40 MPa, the peak deviatoric stress and residual strength increased by 105.76% and 328%, respectively. To better predict the damage evolution of marble under cyclic loading, a new statistical damage constitutive model is proposed. The model incorporates Weibull distribution and the Drucker–Prager failure criterion, providing an accurate representation of the damage evolution process under varying confining pressures. Finally, the model is validated through comparison with experimental data, demonstrating its effectiveness.
To investigate the damage deterioration and seepage evolution of bedded slate under cyclic axial loading–unloading, triaxial tests were conducted on specimens with bedding angles of 0°, 30°, 45°, 60° and 90° under 10 MPa confining pressure and 5 MPa pore pressure. The study systematically analyzed the influence of bedd...

To accurately predict the tensile fatigue life of reinforced thermoplastic pipes (RTPs) and clarify the mechanism of fatigue damage evolution, this research proposes a multiscale analytical model based on continuum damage mechanics (CDM). Built upon the three‐dimensional constitutive relations of RTPs and the load–de...

Accidental detonation under mechanical loading highlights the importance of understanding the dynamic damage behaviour of polymer‐bonded explosives (PBXs). For aluminium‐containing PBXs, systematic characterization of strain‐rate‐dependent and time‐dependent responses remains limited. In this study, the compressive b...
This study presents a numerical approach for simulating the stress-strain behavior of high-modulus polyethylene (HMPE) and polyester (polyethylene terephthalate, PET) multifilaments subjected to progressive dynamic tensile loading cycles. Experimental tests were performed under force-controlled conditions, with a fixed...
