Laser induced cavitation: to understand viscoelastic materials behavior at high strain rates
Tracking full-field deformations using SpatioTemporally Adaptive Quadtree Mesh Digital Image Correlation (STAQ-DIC)

 

Our Mission

Dr. Yang’s research interests include developing analytical tools and experimental techniques to study viscoelastic materials behavior, dynamic instabilities, and material failure under extreme loading conditions. He is currently experimentally characterizing and modeling the dynamic, nonlinear behavior of viscoelastic materials, including hydrogels, biological tissues, and foam materials, under various strain-rate (10^-4 ~ 10^7 s^-1) dynamic loading. Yang’s work also focuses on leveraging state-of-the-art machine learning and data-driven methods to keep improving 2D and 3D full-field deformation measurement (e.g., digital image correlation, digital volume correlation, particle tracking) and other material characterization experimental techniques.

Research Interests

  • Solid mechanics: Visco-hyperelastic material behavior under extreme loading conditions
  • Experimental mechanics: machine learning & data-driven material characterization
  • Full-field deformation measurements: digital image correlation, digital volume correlation, and particle tracking
  • Laser induced inertial cavitation in hydrogels and biological materials
  • Dynamic instability in viscoelastic materials

About Our Group

Dr. Jin Yang joined the Department of Aerospace Engineering & Engineering Mechanics at UT-Austin as an assistant professor in Fall 2022. He received his B.En. in Engineering Mechanics from Tsinghua University in 2013. He received his doctorate in 2019 from the California Institute of Technology, where he developed fast, accurate, adaptive-mesh augmented Lagrangian digital image/volume correlation (ALDIC/ALDVC) methods to measure 2D/3D full-field deformations quantitatively. After his graduate studies, he was a Postdoctoral Research Associate at the University of Wisconsin-Madison between 2019 and 2022, where his research focused on developing a micro-cavitation-based rheometry method to characterize viscoelastic properties of soft gel-like materials at ultra-high strain rates by utilizing laser-induced cavitation experiments. He is the recipient of the Haythornthwaite Seed Grant from ASME and the International Congress of Theoretical and Applied Mechanics (ICTAM) fellowship.
