Abstract :
SPH is a meshfree numerical method that allows the possibility of easily modeling flows with a complex geometry or flows where large deformations or the appearance of a free surface occurs. It is widely used for hypervelocity impact problems. This paper introduces the basic principles of SPH method. Major advantages and disadvantages of SPH method are discussed and listed. Application of SPH method in hypervelocity impact is summarized and numerical case is analyzed.
