Sentence examples for cross section distortion from inspiring English sources
An analytical elastic distortional buckling theory is formulated in the chapter to investigate the elastic structural behavior of I-sections with very slender webs where cross section distortion in terms of local buckling of the web-plate and overall distortional buckling of the I- sections are fully incorporated.
The reduction in capacity due to cross section distortion has been quantified.
The behaviour of thin-walled structures is deeply influenced by non-uniform torsion and cross section distortion.
The effects of cross section distortion on buckling capacity were investigated for beams with single and double overhangs.
A significance-based optimization method of the parameters was proposed based on the finite element (FE) simulation, and the significance analysis of the processing parameters on the forming quality in terms of the maximum wall thinning ratio and the maximum cross section distortion degree was implemented using the fractional factorial design.
The cross-section distortion is considered in the limit case.
The main idea in this paper is that the cross-section distortion can be minimized by regulating the pre-bending radius at the first stage.
In double-stage forming, the bending radius at the pre-bending stage is assumed to be a key parameter to avoid cross-section distortion.
The qualified bent tube with the wall thinning of 11.43%, the cross-section distortion of 2.69% and the wrinkling height less than 2% is then obtained.
The cross-section distortion of thin-walled beams of open section assembled of three plates with two axis of symmetry is considered analytically.
Using the factor of ovality to measure the pipe cross-section distortion, it is found that the cross-section distortion is more severe for the buckled section of the pipe in the moving part of the split box in comparison to its fixed part.
