Die Design and Finite Element Analysis of Welding Seams during Aluminum Alloy Tube Extrusion

open access: yesMetals, 2023
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

Buckling and strength analysis of panels with discrete stiffness tailoring [PDF]

open access: yes, 2019
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.

open access: yesSen'i Gakkaishi, 1991
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
