Calculations of the stress tensor under Symmetric cylindrical shock wave loading
Abstract
The calculation of the components of the stress tensor under symmetric cylindrical shock wave loading, when the pressure impulse of cylindrical symmetry is being spread uniformly along the surface of an infinite cylindrical elastic body, have been carried out. The objective of these calculations is to assess with a sufficient approximation the stressdeformed state in samples during low intensity axissymmetric shock wave loading. The necessity of such an assessment is grounded on a wide utilization and practical applications of shock wave axissymmetric loading used in the explosive processing of advanced materials. Tile main assumptions made at the initial stage of these calculations are: elasticity and isotropy of medium, constancy of the sound speed and Lame elasticity constants, and medium boundary conditions of cylindrical symmetry. Subsequently, the removal of some assumptions during the investigation process makes possible to take into account effects engendered by boundary conditions' asymmetry and changes in the sound speed and Lame constants These changes are caused by irreversible thermal transformations going on in the medium. Well known methods for solving differential equations, such as the Fourier method, functions of Bessel, Neumann, and Hankel, equations of Helmholtz, are used in these calculations. These calculations, assuming axial symmetry, aremore »

Experimental study of effective stress response of sand under water wave loading
This paper presents experimental wavesediment interaction data obtained in a 17.1 m long wave tank facility. Pore water pressures as well as total stresses were measured to determine the effective stress response of a medium grained sand subjected to wave heights up to 0.28 m. The results were compared with the theory presented by Yamamoto at the 1978 OTC. 
Effect of loading path on fatigue degradation and stressstrain response of glass fabric composites under tension/torsion biaxial cyclic loading
It has been well recognized that the fatigue failure characteristics of fiber reinforced composites under tension/torsion biaxial loading are different from those under uniaxial loading. In many cases, biaxial loads are proportionally applied to specimens and their loading path is shown as a straight line on the normal and shear stresses map. However, innumerable loading paths exist which give the same final stress state under nonproportional biaxial loading. It was revealed in the previous research of the authors that the difference in loading mode and sequence of shear stress under tension/torsion biaxial loading apparently affects the fatigue characteristics such asmore »
