Abstract During the injection of carbon dioxide (CO 2 ) for CO capture and storage (CCS) operations, near-well (including casing, cement, rock around it) can undergo several thermal loadings. These loadings significantly increase or decrease pore pressure thus lead to mechanical failure cement sheath formation. When these failures appear in caprock, they compromise integrity site. The understan...
The behavior of elastic waves in a three-dimensional isotropic incompressible material is studied. Unlike compressible elastodynamics, where there are nonlinear interactions of shear and pressure waves, with incompressible elastodynamics the only waves present are shear waves. In an isotropic system, shear waves are linearly degenerate, and therefore global solutions to the perturbative incompr...
The effects of microwave and steam treatment were analyzed relative to the immediate (thermo-hygro-plasticity) post-assessed (permanent changes) properties wood. study was conducted using European beech (Fagus sylvatica L.) standard 1.5 times up-scaled (only for microwave-heated reference samples) bending specimens tested in a static three-point loading mode. plasticized by heat moisture (1) se...
An extension of the contour integral method (CIM) for the computation of stress intensity factors for loaded cracks is presented. Numerical solutions of the two-dimensional linear elasticity equations are computed with the p-version of the generalized finite element method. Polynomial enrichment functions as well as enrichment with near crack tip asymptotic expansion are used. The robustness of...
If the 1908 Tunguska cosmic body (TCB) explosion involved a comet, compressional heating of the comet was expected to create hydrogen and deuterium plasma. The velocity distribution of protons and deuterons in this plasma is not expected to be the Maxwell-Boltzmann distribution. It is shown that the use of a generalized momentum distribution leads to substantial increases of deuteron fusion rat...
Abstract The promising phase-field method has been intensively studied for crack approximation in brittle materials. realistic representation of material degradation at a fully evolved is still one the main challenges. Several energy split formulations have postulated to describe evolution physically. A recent approach based on concept representative elements (RCE) Storm et al. (The fracture: a...
