This project involved redesigning a hydroforming rig to bulge copper tubes. Hydroforming uses pressure to form complex shapes. The student redesigned and manufactured the rig, then carried out expansion testing using a design of experiments approach to identify critical parameters. A finite element model was developed and validated against experimental results. Tensile testing obtained the annealed copper tube material properties. The stress-strain relationship was analyzed to draw conclusions.
The world of manufacturing world is broadly classified into two main categories such as cold working and hot
working process. The process in the manufacturing world which is conducted above the recrystallization
temperature are called as hot working process while the process which is conducted below the recrystallization
temperature of the work piece is called cold working process.in the above categorization, the casting and
forging process is considered as the hot working process while other processes were kept under cold working
process category. The process for our review is forging and in our research paper, we are focusing on the
forging process, the types of forging process and the various parameters that are considered as a tool for the
process optimization of the forging.

Developing A Prediction Model for Tensile Elastic Modulus of Steel Fiber – Ce...IJRESJOURNAL
ABSTRACT: This paper attempts to develop a prediction model that can be used in line with prescribed laboratory experiments for indirect tensile test such that tensile elastic modulus can be predicted for cement stabilized lateritic soil reinforced with steel fiber using measured properties of the material. The results of the tensile elastic modulus obtained from the Derived Prediction Model almost nearly replicates that obtained from calculations from laboratory experimentation. Results obtained revealed that both the predicted values and calculated values have a linear correlation with an R2 of 96.4%. On this basis the Derived Prediction Model can be said to be valid within the limits of the study.

Design & Analysis of Composite Propeller ShaftIJSRD
A Propeller Shaft is the connection between the transmission and the rear axle of the vehicles. The function of propeller shaft is to transmit the power from engine to the rear wheel in case of front engine drive vehicle. High quality steel (Steel SM45) is most commonly used material. The steel drive shaft consists of three universal joints, a center supporting bearing and a bracket, which increase the total weight of a system. The Power transmission can be improved through reducing its weight. According to previous researches many have done the various experiments to reduce the weight by changing the ply thickness, fiber orientation angle, number of plies but until now no one has studied the effect on the properties of the composite formed by changing volume fraction of carbon fiber & epoxy resin. The focus of this work will be to investigate either replacing steel structure of propeller shaft by composite structure such as carbon fiber & epoxy resin to minimize the cost and weight, also to check the suitability of composite structures by experimental method and software testing.

Monolithic Portal Frame, Portal Frame with corbel and Portal Frame without corbel and their deflections at various loads were observed and derived conclusion which one is efficient among all frames designed and cast.
FEA AND EXPERIMENTAL QUASI-STATIC CRUSHING OF ALUMINIUM HONEYCOMB STRUCTUREVishal Mudka
The honeycomb is a typical cellular structure composed of metals, polymers, ceramics and paper which are commonly used as energy absorbing materials for various engineering applications such as, packaging, protective materials, core materials of sandwich panels, and building materials. A series of experiments were conducted on hexagonal aluminium honeycomb specimens in their principal loading direction i.e. Out-of-plane (along the direction of cell axis parallel to the thickness of specimen) as per the ASTM C-365 standards. In both the cases, load-displacement characteristics and the deformation mechanisms were studied in order to assess energy absorbing capacities. The study also focuses on the crushing behavior of honeycomb under the above loading configuration. This experimental results are compared with FEA using Ls-Dyna and Hypermesh.
Finite element simulation using Ls-Dyna is carried out on aluminium honeycomb. A comparison of energy absorption capacities of this material obtained from the experiment simulation is made. The results obtained from the simulation of aluminium honeycomb are in good agreement with experimental results.

Experimental investigation of reinforcement couplers as replacement of bent-barrk pandey
In structural concrete, the provisions for anchorage of straight bars and hooks normally present detailing problems due to conjunction of reinforcement bar. Mechanical anchorage device eliminates detailing problems when conjunction of reinforcement bar. This paper represents the various method of mechanical anchorage and past work carried out on mechanical anchorage which shows the effectiveness of mechanical anchorage method over the most commonly used method.

Hydroforming of Tubes
Student: Eamonn Brennan, Mechanical And Manufacturing Engineering Supervisor: Dr. Bryan MacDonald
Hydroforming is a metal forming process where pressure is used to form complex shapes.
The aim of this project is to redesign and update a hydroforming rig to be capable of
bulging copper tubes. Expansion testing will then be carried out, and a design of
experiments methodology will be used to identify the critical process parameters and their
effect on the final product. A finite element model of this process will then be developed,
and validated against obtained experimental results.
Project Introduction

help throughout this project. I would also like to thank my family and fellow students for their continued support and
encouragement.
Tasks Performed Rig Design and Manufacture
Finite Element Analysis Testing (Bulge and Tensile)
• In order to specify the equipment for the hydroforming rig, the
required pressure was calculated.
• Concept designs for the rig were developed, and final drawings
dimensioned for the equipment specified.
• The rig was manufactured and assembled, and tests carried out to
investigate the relationship between the pressure supplied and the
bulge achieved.
• The seals were redesigned in order to achieve a higher pressure that
could be delivered to a tube to be formed in the rig.
• The FEA model was initially constructed using 8 node quadrilateral
elements and testing was carried out, and was then redesigned to
use Shell elements to achieve a more accurate solution.
• Copper tubes were annealed in order to reduce their strength and
allow them to be more easily formed.
• Tensile testing was carried out in order to obtain the material
properties of the annealed tubes.
• A stress and strain analysis was conducted.
• All results were recorded and discussed, and conclusions were drawn
