On Formulations for Modeling Pressurized Cracks Within Phase-Field Methods for Fracture
Andre Costa, Tianchen Hu, John Dolbow
Over the past few decades, the phase-field method for fracture has seen widespread appeal due to the many benefits associated with its ability to regularize a sharp crack geometry.…
Phonon promoted charge density wave in topological kagome metal ScVSn
Yong Hu, Junzhang Ma, Yinxiang Li +21
Charge density wave (CDW) orders in vanadium-based kagome metals have recently received tremendous attention due to their unique properties and intricate interplay with exotic corr…
Optical spectroscopy and band structure calculations of structural phase transition in the Vanadium-based kagome metal ScVSn
Tianchen Hu, Hanqi Pi, Shuxiang Xu +11
In condensed matter physics, materials with kagome lattice display a range of exotic quantum states, including charge density wave (CDW), superconductivity and magnetism. Recently,…
Strong nonlinear optical response and transient symmetry switching in Type-II Weyl semimetal -WP2
Tianchen Hu, Bo Su, Liyu Shi +13
The topological Weyl semimetals with peculiar band structure exhibit novel nonlinear optical enhancement phenomena even for light at optical wavelengths. While many intriguing nonl…
Revealing the frequency-dependent oscillations in the nonlinear terahertz response induced by the Josephson current
Sijie Zhang, Zhiyuan Sun, Qiaomei Liu +11
Nonlinear responses of superconductors to intense terahertz radiation has been an active research frontier. Using terahertz pump-terahertz probe spectroscopy, we investigate the c-…
A Variational Phase-Field Model For Ductile Fracture with Coalescence Dissipation
Tianchen Hu, Brandon Talamini, Andrew J. Stershic +2
A novel phase-field for ductile fracture model is presented. The model is developed within a consistent variational framework in the context of finite-deformation kinematics. A nov…
A phase-field formulation for dynamic cohesive fracture
Rudy J. M. Geelen, Yingjie Liu, Tianchen Hu +2
We extend a phase-field/gradient damage formulation for cohesive fracture to the dynamic case. The model is characterized by a regularized fracture energy that is linear in the dam…
