Abstract

The article analyzes the stress-strain state in the zone of plastic deformation during special caliber rolling. The principle of caliber rolling technology is described, which makes it possible to combine shear and compression deformations in the cross-section of metals, alloys, and metal-matrix composites. The analysis results of stresses and strains during shear rolling in a diamond pass, which included compressive strains that had not been considered in previous studies, revealed that localization or point inversion of stresses and strains is observed in the plastic deformation zone. Stress and strain are localized along the minor and major diagonals of the diamond pass.
在口径轧制过程中,在金属材料横截面上实现简单剪切的可能性
分析了特口径轧制过程中塑性变形区的应力-应变状态。介绍了口径轧制技术的原理,该技术使金属、合金和金属基复合材料的剪切变形和压缩变形结合在一起成为可能。对金刚石孔道剪切轧制过程的应力应变分析结果表明,在塑性变形区存在应力应变局部化或点反转现象,其中包括以往研究未考虑的压应变。应力和应变沿金刚石孔道的主要对角线和次要对角线分布。

期刊介绍: Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
