للكاتب : A.M. KOHAIL Mech Eng., Prod. Dept.(R), MTC , Cairo ABSTRACT Laser drilling has been widely used in industry. The laser drilling process occurs when the laser beam is focused with enough intensity to melt and vaporize the drilled substrate. The high throughput energy rate is one of the most important laser drilling advantages. Most of laser material processing …

On the one hand, a model describing the physico-chemical processes which occur within the bed of solid. On the other hand, C.F.D.the topic of this study, This model must include …

للكاتب : Elhabak, A.M. and Adly, M. Mech. Design & Prod. Dept., Faculty of Engineering, Cairo University   ABSTRACT The knee in the acoustic emission cumulative counts curve has been proposed as a possible solution to the absence of a characteristic yielding point in the stress-strain curve of composite materials. Yield strength could eventually be adopted in the engineering design as …

This experimental work consists …

 للكاتب : N. M. Ashour Faculty Engineering, Mataria, Cairo, Helwan University, Egypt ABSTRACT On large thrust bearings, the geometry of the bearing pad surface is affected appreciably by deformation. In a spring supported thrust pad bearing, the deformation caused by the generated pressure and thermal gradient yields surface profiles of opposite shapes. The thermoelastic analysis performed here makes it possible …
