Abstract Based on the distribution and layer characteristics of prestressed steel wire-wound cylinder four-column hydraulic press, its supporting parts not only bear constant stress caused by internal pressure, but also withstand alternating cylinder, then produce gradual accumulation plastic deformation. This paper uses theoretical calculation formulas to solve corresponding parameters, establ...

Abstract This research investigates the effects of cut-out on dynamic behaviour functionally graded carbon nanotube reinforced composite (FGCNTRC) plates. Finite element method (FEM) is utilized and SHELL181 type ANSYS Workbench 17.2 program utilized. To understand vibration characteristics FG plates, various shapes cut-outs such as triangular, square, rectangular, hexagonal, circular etc are c...

Hybrid moulds are an increasingly considered alternative for prototype series or short production runs. This type of tools resorts on the use Rapid Prototyping and Tooling (RPT) to produce moulding elements (blocks other inserts). study was developed using a hybrid injection mould with exchangeable that were produced by additive manufacturing (AM), namely vacuum epoxy casting, stereolithography...

Hardfacing is carried out whenever a local improvement of the mechanical properties metallic parts demanded. In this regard, gas metal arc welding technology one most popular choices. One decisive factor welded joint quality governed by heat affected zone. The present paper proposes simulation methodology that can be employed for capturing temperature gradients in any location base metal, when ...

Abstract Applications of sandwich composites are increasing as they continue to develop. The reason for the growth in development and rising demand numerous industries is due its ability achieve high stiffness strength, while simultaneously being lightweight comparison traditional materials. 3D printed plastic hollow core were focused on this study where a bioplastic, Polylactic Acid (PLA), was...

The desired preloading effect of a hydraulic press frame parts (upper/lower semi-circular beams and columns) with Pre-Tightening Stress (PTS) by means Winding Steel Wires (WSW), which is directly related to the reliability normal safe operation press. deformation Hydraulic Press Column (HPC) an important indicator optimal As technical bottleneck, continuous cumulative HPC under seven time-varyi...

The responses of the structures used in engineering applications under effects static and dynamic forces are significant design phase. Determination response for a structure is initially performed by evaluation free vibration characteristics that mode shape frequencies. This paper presents modal analyses tapered aircraft wing consist NACA4415 different common materials aviation industry. Furthe...

This paper focuses on aerodynamic analysis over a 3D cambered wing with dimple-like surface modification. Application of the golf ball dimples airfoils is predicted to be good alternative for drag reduction. A allows smooth and controlled flight. Models wings based NACA 2412 airfoil were created investigate dimple effect. comparative study carried out between models inward outward at 50% chord ...
