The study on the mechanical response of deep rock under hydromechanical couplings condition can guide safe excavation and stability evaluation tunnel engineering. effects monotonic loading cyclic properties granite 5 MPa pore water pressure 10 confining were studied by laboratory tests. Before peak stress, permeability was significantly higher than that loading, increased sharply after stress. ...
• Multiaxial fatigue models for notches are analysed. The geometry is an infinite plate with a circular hole. evolution of the predictions increasing hole radius not monotonic. This non-monotonic observed experimentally. work shows analysis several multiaxial notches: Navarro-Rios’ model, which analyses interaction between crack and its associated plastic zone material microstructural barriers,...
INTRODUCTION In the United States, there are over 300,000 hip fractures annually, resulting in over $13 billion in medical costs (1). About 90% of these have been reported to be the consequence of falls (1). The remaining 10% are thought to be the result of fatigue of the bone tissue (spontaneous fracture). Repeated falls may increase fracture risk by affecting the integrity of the bone tissue;...
This work explores the monotonic and cyclic behaviors of filled, natural rubber. Results of stress-strain experiments conducted under stress states of simple, planar, and equibiaxial tension are presented. The ability of hyperelastic models to capture the observed response, as well as recent developments in constitutive modeling of filled rubber such as the consequences of the Mullins effect, a...
Piping systems are a representative social infrastructure to provide oil, gas, and water. Damage piping may cause serious consequences, such as fire, water outage, environmental pollution. Therefore, need be protected from natural disasters, earthquakes. Earthquakes deformation that exceeds design criteria. For example, large relative displacements liquefaction of the ground resulting in loss s...
Composite reinforcing bars (rebars) that are used in concrete members with high performance (strength and durability) properties could have beneficial effects on the behavior of these members. This is especially vital when a building is constructed in an aggressive environment, for instance a corrosive environment. Although tension capacity/weight (or volume) ratios in composite rebars (carbon ...
