يستعرض البحث أضرار الانفجارات على المباني والمنشآت الهندسية وآلية توصيف هذه الأضرار ونمذجة المنشآت باستخدام البرامج الحاسوبية لدراسة طرائق الترميم و توقع سلوك المنشأ المتضرر.
This work theoretically investigates the nonlinear behaviour of
reinforced concrete dee aimed topcantilever beams with concentrated loads
at their free ends The study is aimed to in investigate the behaviour
and respnse of such deep cantilever bea
ms, and to help structural
engineers to design and adopt appropriate reinforcement detailing of
such elements. A complete review of literature on this subject is
made.
The use of modern methodologies and techniques a new approach to evaluate the
process of engineering design in the industry pay to use in evaluating the speed in large
cans mechanisms design.
The gearbox that is designed for big vehicles for off-r
oad driving conditions need
portal axle which installed between the wheel and the axle shaft to give higher ground
clearance to the vehicle.
The modeling and simulation of spur gear which contacted with portal axle is
important to predict the actual motion behavior, but it's so complicated to study.
In this study, it'll analysis the portal axle by using finite element method (FEM),
modal analysis will simulated on three different combinations of gear train system, the
three gear trains being analyzed are: gear train without idler gear, one idler gear and two
idler gears.
FEM static stress analysis will also simulated on three different gear train to study
the gear teeth bending stress and contact stress behavior of the gear trains in different
angular positions from °0 to °18 degree.
It is a cross in the hydraulic systems with long pipes case modeling of the hardest and most important cases in search. Of the most important and is considered Query to achieve study the changing resistance model is used to describe the changing liqu
id flow in the tube. As described by knowing the nature of the shear stress to the pipe wall and also know the nature of the flow ( laminar or turbulent ). The results of simulations of hydraulice shock caused by the sadden move of the hydraulic control valve which studied in the following cases:
1- Hard to improve the discharge of the pump rate.
2- Improve the discharge of the pump variable rate finally; compare the results of computer simulations with experimental results.
In this research, a simple cylinder concrete model was analyzed. This model is simple and single in the center of cylinder for plain reinforcement and cubic model for deformed reinforcement. If we made a tension load on the reinforcement bar until we
reach to the destruction by using non-linear analysis for the three dimension subjects by using the finite element ANSYS to study the bond stress between the concrete and the reinforcement.
