NUMERICAL SIMULATION OF AN UNDERWATER EXPLOSION BY SPH METHOD
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2016, Vol 61, Issue 1
Abstract
This paper presents theoretical and practical fundamentals regarding numerical analysis of an underwater explosion. Its parameters and effects upon submerged structures represent the aim of the numerical analysis by Smoothed Particles Hydrodynamics (SPH). SPH method is a version of a more general numerical method, named free particle method. The fundamentals of explosion theory and of the SPH method are supposed to be known, so this paper intends to present only the particularities of an underwater explosion and how its parameters and effects can be modeled by SPH method. The example finishing the paper represents an available numerical model for such problems.

This work investigates the geometry of the homogeneous representation of the group of proper rigid-body displacements. In particular it is shown that there is a birationaltransformationfromtheStudyquadrictothevarietydete...
ON THE DYNAMIC BEHAVIOR OF ELASTIC FRAME STRUCTURES WITH BASE IMPOSED HARMONIC DISPLACEMENT
The dynamic response of an elastic shear frame structure to imposed lateral harmonic displacement of the base slab is analyzed within frequency ranges placed below and above natural frequencies. It is shown that between...
DIRECT AND INVERSE PROBLEMS FOR AN INHOMOGENEOUS MEDIUM
The plane problem for an inhomogeneous medium is analyzed in this paper by using the cnoidal representation of the material inhomogeneity. This representation approximates the distribution of elastic properties in the ma...
