Stress Analysis and Energy Estimation in Cold-Roll Forming Process

In this article, stress analysis and energy estimation during cold-roll forming of symmetrical channel sections have been discussed. Geometry of sheet strip is pre-estimated by a shape function. Then longitudinal, transversal and shear strains have been calculated. Using both the Levy-Mises and the Prandtl Reuss equations, and also considering the Bauschinger effect, stress distributions have b...

Selecting Optimal Dimensions of Internal Tube in Tube-in-Tube Structural Systems Based on Structural Parameters

Tubular structural systems are one of the most common types of systems in high-rise structures. In the early days of this system, there were imperfections in its design which were overcome over time. The most important modification to rectify these defects is the use of a series of internal frames in addition to the peripheral frames and new systems in the center of the plan to eliminate design...

Experimental Study on Warm Incremental Tube Forming of AA6063 Aluminum Tubes

Effect of temperature on formability of AA6063 aluminum tubes in incremental forming process was investigated. Experiments are performed on AA6063 aluminum tubes. A spirally moving tool incrementally expands the tube wall. The tube is clamped from both ends while the deformation zone is not in contact with the die. A circumferential heating system is used to heat the tube due to the low formabi...
