Biomechanics is the main research field. This field mainly studies the nonlinear strain analysis method of arterial wall, the expression of nonlinear stress-strain relationship, the strain distribution, the stress distribution and the residual stress of arterial wall. Among them, I successfully developed a new nonlinear strain analysis method and determined the standard experimental method of arterial wall static mechanics. The mathematical expression and nonlinear physical parameters of nonlinear stress-strain relationship of arterial wall are analyzed. He has successively undertaken two national natural science foundation projects:199765438+"Study on Mechanical Properties of Arterial Wall" from February 2000 to February 2000, with the project number 19772006. 65438+February 2003 to 65438+February 2006 "Study on the Mechanical Mechanism of Aortic Arch Dissection Aneurysm", ProjectNo. 103720 10.
In the field of experimental detection mechanics, we have studied the automatic detection technology of experimental machine, residual stress detection and analysis technology, magnetic memory detection technology, fatigue test and reliability analysis for many years.
