This study focuses on the internal shaft friction of open-ended tubular piles induced by jointed weak rock plugs. To investigate bearing mechanism plug, push-up load tests were carried out mudstone inside a pile. The discrete-element method (DEM) was used in order to consider heterogeneity and reproduce discrete nature mass. A flat-joint model mechanical behavior mudstone, smooth-joint contact replicate natural joints. using calibrated properties mudstone. effects joint density dip examined...
The nonlinear characteristics of unsteady combustion solid propellants are investigated numerically. adopted mathematical models the quasi-steady homogeneous one-dimensional (QSHOD) model and Zel'dovich-Novozhilov (ZN) model, widely used in instability study. A numerical algorithm based on spectral decomposition is constructed for two according to their similar governing equations. different dynamical features driven by pressure excitation compared. results show responses still qualitatively...
Abstract Aging during storage and confinement pressure launch are the two major loading conditions that affect integrity of solid rocket motors. In comparison to other component materials, propellants, as highly filled composites, have a low modulus fracture toughness therefore common sources failure. The key improving motor is in assessing health propellants or launch. To address this issue, we revised previous model for progressive damage viscoelasticity include effect chemical aging...
Destress blasting is gradually used in deep tunnel excavation to pretreat the development face, which can migrate stress concentration ahead of face rock mass, thus reducing danger burst. As destress detonates before normal holes, it bound have an influence on excavation, this key problem needs be thoroughly investigated guarantee security construction. For reason, damage and evolution mechanisms section after blasting, as well impacts various full-face were explored paper. The results...
