High-Velocity Tension-Impact Tests
Abstract
Data are presented which definitely show that high-velocity tests are essential to reveal the true dynamic properties of materials. The results obtained further indicate that in the selection of materials for use under conditions involving dynamic loading the following three significant factors must be considered: 1. The transition velocity within which normal material behavior may be expected. 2. The ratio of total energy value to mass or volume of material involved. 3. The effect of surface irregularities such as tool marks, size and form of fillets, etc. The high-velocity tension-impact machine designed and built for this investigation is described, and the mathematical derivation of the equation used to calculate the energy required for rupture is given. Diagrams and photographs of typical fracture transitions are presented, showing the effect of velocity on both ferrous and non-ferrous materials
