Influence of hydraulic brakes typical parameters on the process of recoiling mass breaking
Vojnotehnički Glasnik, 1998 The mathematical model for providing typical parameters of the process of breaking of recoiling mass on an artillery gun is presented. The model of hydraulic brakes with some discrete distribution of orifice surfaces in the cylinder is defined.

Radiation Loading on Pistons and Arrays of Pistons [PDF]
The Journal of the Acoustical Society of America, 1956 Expressions are presented whereby the radiation load on a piston or an array of pistons may be determined from physical principles and factors illustrated by various types of well-known radiating surfaces, wave guides, and conical horns. On the assumption that the radiation loading on a piston may be defined sufficiently by its low- and high-frequency ...

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
Advanced Engineering Materials, EarlyView.The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.
