The purpose of this research is to look at the buckling behavior of axially loaded, symmetrical laminated composite rectangular plates with simple support boundary conditions all around. In this work, balance equations based on Classical Plate Theory (CPT) produced from Kirchhoff assumptions are used to present formulas that determine the critical...

Solid state joining techniques are increasingly used in joining different types of materials, in this work TP347HFG austenitic stainless steel will be welded with HiPerFer ferritic stainless-steel alloy due to their similarity in their properties to some extent after making heat treatment to ferritic alloy in addition to difference in their cost wh...

This paper presents the effect of composite materials that included limited damping material on vibrating structures modal. The current study selected two symmetrical laminates having [(0/90) 66 ] S carbon-epoxyE502, and glass-epoxyCG202. Measurements are carried out on structure of the spur gears by using hammer test. Comparisons of the results of...

The aim of this work is to investigate analytical (Classical theory) and [ANSYS Parametric Design Language (APDL)] analysis of laminate composite plate. The free vibration analysis with two boundary conditions simply supported (SSSS) & clamped ends (CCCC) are taken into account in this work. The equations of motion that governs the predication of d...

Improving the mechanical properties of additive manufacturing materials has led to an increase in the use of these materials in industry on an unprecedented scale. Acrylonitrile butadiene styreneM30 (ABS M30) samples were fabricated by the Fused Decomposition manufacturing (FDM) process and then pre-coated with a thin layer of Cr and Cu through the...

The dynamic analysis of the fused deposition modeling (FDM) products is one of the most important topics in investigation of 3D manufacturing nowadays. The purpose of this paper to present the dynamic properties of FDM parts made from ULTEM 1010 with different coating layer thicknesses. The coating process consists of two stages: physical vapor dep...

The purpose of this research was to select the optimal materials for various spur gear designs. Three gears were designed using three variables: the number of teeth, the material weight constant, and the Lewis factor form. The objective function was set to minimize mass based on the restriction of bending fatigue failure criteria and bending streng...

A novel and new reconfigurable gripper was designed, conceptualized, and demonstrated in the previous study. The new gripper comprises six modular fingers that can rotate and clamp simultaneously. The finger assembly consists of two links, the finger-arm and the finger base. During grasping the desired object, the finger arm is in contact directly...

An entirely new reconfigurable gripper is designed and shown in this paper. The new gripper comprises six modular fingers, which can be rearranged to form any number of fingers between three and six. CAD, CAM, CAE, and PCB software Fusion 360 was used to design the gripper. Also, the gripper fingers are rotatable, so the finger bases can touch each...

The manipulator robots are devices used to perform dangerous tasks and impossible missions that humans cannot perform without paying too much effort and time. Therefore, they are used in a wide range of applications without any interaction with humans. This type of robot can carry different types of end-effectors to perform various kinds of applica...

In this paper the combination of the theoretical, numerical and experimental study of stresses, deflection and free vibration of (stainless steel mesh, random E-fiberglass, and Epoxy resin) anti-symmetrically laminated composite plates subjected to a uniformly distributed load for simply supported boundary condition are investigated. The theoretica...

In this study, the rotations around all three axes are performed practically by designing a small prototype for the (3-Axis Stabilized Satellite). The prototype shown in this research placed in space by using suitable mechanism. The panels is neglected for the design to be lighter in weight and offer more space for the designed prototype to rotate...

This work covers the investigation of the effects of the space environments factors on the spacecraft structure. The satellite operates on a low earth orbit at circular (500,500) km, and subjected to different torques in space environments. The purpose of this paper is to develop the satellite structure design and tested to obtain the mechanical be...

In this research a strain gage based on two components were carried out to measure the two components of the resultant cutting force, namely, the tangential and feed cutting forces on an engine lathe during the cutting. The focus of the present study is to find a correlation between cutting forces and surface roughness in turning, and to use mathem...

This paper investigated a new method to measure the cutting forces in turning operation using current sensors. The relationships between the various factors, which affect the performance of the spindle servo motor in a lathe machine was investigated. Current signals of the ac servomotor in lathe machine are estimated in turning operation. Experimen...
