高压力学方法及研究进展

High pressure mechanics has set off a great wave of interdisciplinary researches among materials science and geosciences, providing solutions for the synthesis of novel materials with high challenge, improvement of mechanical properties of materials, and understanding of the seismic anisotropy and geodynamics in the inner of the Earth. Here we have reviewed recent research progress in high pressure mechanics, which includes diamond anvil cell combined with X-ray diffraction in a radial geometry, rotational diamond anvil cell induced shear strain, high pressure torsion-imposed shear strain, D-DIA induced plastic deformation and shock compression induced plastic deformation. These findings show the unique coupling effect of compression constraint and shear stress on tuning the structure, properties and mechanical behavior of materials, revealing the value and potential of high-pressure mechanics in research and application.
