Regional Stiffness and Hardening Indices: New Indicators Derived from Multidimensional Dynamic CTA for Aneurysm Risk Assessment. [PDF]
Adv Sci (Weinh)Two new indicators are derived from nonlinear stress–strain behavior obtained through in vivo biomechanical analysis of patient‐specific multidimensional dynamic computed tomography angiography. The regional stiffness index indicates the average stiffness while the hardening index reflects the pace of strain hardening.

Reconstruction of Wing Structure Deformation Based on Particle Swarm Optimization Ridge Regression
International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022 In this paper, a typical airfoil aluminum plate structure is taken as the research object. A structural deformation monitoring and reconstruction method, PSO‐RR (particle swarm optimization‐ridge regression) algorithm, is proposed. A variety of different complex load cases are applied to the airfoil structure, and the strain values at some specific ...
