Electromagnetic Force Distribution and Axial Deformation Uniformity Analysis of Dual-Coil Electromagnetic Tube Compression Method

IEEE Access, 2020
In the conventional electromagnetic tube expansion, axial distribution of the electromagnetic force is not uniform along the workpiece. This results in uneven axial deformation of the deformed tube and restricts the full industrial implementation of this

Performance-Based Multi-Objective Optimization of Four-Limb CFST Lattice Columns

Buildings
In this paper, the low-cycle reciprocating load test was carried out on four-limb concrete-filled steel tubular (CFST) lattice columns with different slenderness ratios and axial compression ratios, and the seismic performance was studied.

How do compression and flexion-compression injuries destabilize the spine? A novel in vitro protocol for analyzing three-dimensional biomechanical instability

Frontiers in Bioengineering and Biotechnology
IntroductionUnstable traumatic spinal injuries require surgical stabilization. However, biomechanical instability of specific spinal injuries has been little investigated, although restoring stability represents a primary goal of surgical treatment. This
