WebJun 18, 2015 · Say that a small metal ball impacts a long thin cylindrical rod from above (let's say height of around 10 cm) in an elastic collision and causes stress waves to propagate left and right from the point of collision. ... I assumed stress wave generation is a fairly well studied problem in mechanical/aerospace engineering, and just wanted to … WebIn this paper, the dynamic stress concentration and scattering of SH-waves by bi-material structures that possess an interface elliptic cavity are investigated. First, by using the complex function method, the Green’s function is constructed. This yields the solution of the displacement field for an elastic half space with a semi-elliptic canyon impacted by an …

WebBiot's poroelastic theory is employed to study stress wave propagation in an infinite slab of arbitrary thickness. The frequency equation is obtained each for pervious and impervious … WebThe cylindrical wave propagation in jointed rock mass is a great concern of underground structure safety. In this paper, the time-domain recursive method (TDRM) is extended to investigate cylindrical stress wave propagation through a rock joint with nonlinear normal deformation. WebNov 22, 2024 · The wave function expansion method and multi-polar coordinates are adopted to derive the formula for dynamic stress concentration factor (DSCF) of tunnel surrounding rock under cylindrical P-waves. Combined with a specific engineering case, the influence of frequency and scaled distance r * on DSCF is analyzed. ray the dj az
