Dynamics impact mechanics penetration

The price of the advantages of the analytical methods is the necessity to use approximate models. The two-term LIM was employed, wherein the assumption about a linear dependence between the coefficients of the model was used. Cross-section of the reference impactor. Consider now the behavior of this function for small b 1. Finally it must be noted that some generalizations discussed at the end of Section are also valid in this case. However, the stopping time decreases with initial impact velocity for all initial impact angles for the considered system. A model that is based solely on the dependence between the.

The project also required the development of novel thermocouple and stress-gauge systems. In mechanics , an impact is a high force or shock applied over a short time period when two or more bodies collide. From Wikipedia, the free encyclopedia. Siviour, Peifeng Li Sponsor: The cell is reinforced so it will survive in high speed crashes, and so protect the users.

This project focuses on the development of experimental methodology for shock loading of cavitation bubbles in viscous media. Nik Petrinic, Simon Read Sponsor: Small-scale structural tests in controlled laboratory conditions have been carried out in order to provide data for validation of developed modelling tools. Impact resistance decreases with an increase in the modulus of elasticity, which means that stiffer materials will have less impact resistance. A range of different sintered Ti foams has been characterised under compressive loading at a range of strain rates.

Although Newton did not use modern mathematical theory that was nonexistent at that time , his geometrical constructions yielded a correct answer. Contact modelling is an ancient topic, which starts with the works of Hertz and al. The cylindrical cavity expansion model suggested by Sagomonyan was used in that study. It results in a considerable overestimation of the maximum impact force. The impact of a free planar link with a granular material is studied in this research. A library for cavity expansion algorithms, Version 1.
