Time history analysis of displacement and stress fields in thick hollow cylinders subjected to impact loading using analytical method
The radial wave propagation and dynamic behavior of thick hollow cylinders subjected to mechanical impact loading is studied using a general analytical method base on a composition of Bessel functions. The cylinder is assumed in plane strain...
Impact of lameness in Iran’s dairy herds
. It is obvious that eradication of this condition in the herd is not possible. The only logical idea is controlling and reducing lameness incidence to reasonable rates. This needs a deep knowledge of lameness and its impact in the herd. This article review...
Cooling effectiveness of a water drop impinging on a hot surface
We studied, using both experiments and a numerical model, the impact of water droplets on a hot stainless steel surface. Initial substrate temperatures were varied from 50°C to 120°C (low enough to prevent boiling in the drop) and impact velocities...
Development of multiple regression model to estimate the apple’s bruise depth using thermal maps
of agricultural products. In this study, the surface temperature of bruised apples was determined using thermal maps and the bruise depth during a set of factorial experiments in the form of a completely randomized design with two factors, namely impact location...
The influence of impact loading on the fatigue life of EA4T steel
There are many situations where structural components are subjected to combined impact and fatigue loading. It is evident that the impact strength of metallic materials changes following a history of fatigue loads. Similarly, the fatigue behaviour...
The influence of impact loading on the fatigue life of EA4T steel
There are many situations where structural components are subjected to combined impact and fatigue loading such as railway shaft, any rotator shaft which subjected to shock loade, wheel shaft of airplane on the landing and …, It is evident...
