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 has an explicit physics meaning. Thus the competitive crack growth process of geoengineering structures can be simulated by using the developed method, which can consider the stress redistribution duri...

Theoretical and experimental studies have revealed that at small length scales, surface effects contribute significantly to overall elastic deformation. In this paper, we analyze a torsional problem for a nanosized penny-shaped crack in an infinite homogeneous isotropic elastic medium with surface elasticity on the boundary of the crack. The resulting model of deformation leads to a nonclassical mixed boundary value problem which is analyzed using the Hankel transform technique leading to a pair...

Two-dimensional plane strain approaches in fracture mechanics have been used to characterize crack tip constraint of cracked geometries from deep to shallow cracks but neglected out-of-plane crack tip constraint effect. To address the effect of thickness and crack length in three-dimensional crack tip constraint, fully constrained geometries of notched bend bars and unconstrained geometries of center cracked tension panels of deep to shallow cracks in non-hardening and hardening elastic–plastic ...

The double cantilever beam (DCB) specimen has been used extensively to measure the mode I fracture toughness of laminate composites. There are standards which were developed for testing unidirectional (UD) material. In addition, this specimen has been used extensively for multi-directional laminates. Typically, fracture resistance curves are presented. To this end, calculation of the energy release rate is required. For UD specimens, there are expressions for this parameter given in the standard...

In this paper, the effect of creep-fatigue loading condition on crack tip deformation and stress fields of Grade 91 steel at 600 °C at crack initiation and growth is studied. By using finite element debond analysis method, creep-fatigue crack growth tests using C(T) specimens under various load ratios and hold times are simulated, and the effect of creep-fatigue load ratio and hold time on the crack opening profile, equivalent stress, crack-opening stress and triaxiality at crack initiation and ...

Many metal materials possess the transition from strain localization to fracture, the so-called post-necking behavior, during large deformation under tensile load. It is crucial to understand and characterize the transition for the application of these materials. In this paper, the stress state dependence of the transition from strain localization to fracture of Ti–6.5Al–3.5Mo–1.5Zr–0.3Si alloy is characterized and analyzed by carrying out experiments and phase-field modeling. Firstly, tensile t...

Additive manufacturing (AM) has emerged as an alternative tool to overcome the challenges in conventionally processed metallic components. It is gaining wide acceptability because of the superior properties of the manufactured components compared to their wrought processed counterparts. Among the available AM processed materials, austenitic stainless steel 316L is widely explored wherein an excellent strength-ductility trade-off has been reported. However, the mechanisms underlying fracture toug...
