Die Design and Finite Element Analysis of Welding Seams during Aluminum Alloy Tube Extrusion
Hollow tubes are generally manufactured using porthole die extrusion. A finite element software QForm is used to analyze the material flow of aluminum alloy A6061 tubes inside a specially designed porthole die during tube extrusion. High welding pressure

Influence of notch orientation on ductile tearing in SENT specimens [PDF]
There is a growing interest for the use of spiral welded pipes in strain based design related applications. Since the influence of the spiral weld on the plastic behaviour of the pipe is not yet fully understood, further research on this topic is ...

Buckling and strength analysis of panels with discrete stiffness tailoring [PDF]
Continuous variation of stiffness across flat plates has been shown, theoretically, to improve buckling performance by up to 60%. However, steered fibre manufacturing methods cannot achieve the minimum radius of curvature required for improvement whilst ...

Strength of two needle lockstitch seams.
The strengh of two needle lockstitch seams was studied using the theory of the minimum loop strength of thread. In general, the strength of two needle seams F2 is expressed as follows: where θ is a variable which lays between 0 and 1 and is considered to be influenced by sewing factors such as thread combination, thread properties and consumption. Both
