Numerical simulation of explosive fracturing with smoothed particle hydrodynamics
Guo, Zhiming; Shen, Yongxing; Liu, Moubin (CIMNE, 2013)
Text en actes de congrés
Accés obertIn this paper we study explosive fracturing with smoothed particle hydrodynamics (SPH). As a particle based Lagrangian method, SPH is particularly suited to the analysis of fracture due to its full Lagrangian frame and ... -
Numerical simulation of soil-water jet interaction with smoothed particle hydrodynamics
Guo, Zhiming; Shao, Jiaru; Shen, Yongxing; Liu, Moubin (2013)
Text en actes de congrés
Accés restringit per política de l'editorialSmoothed particle hydrodynamics (SPH) is a meshfree, Lagrangian particle method, which has been applied to different areas in sciences and industrial applications. In this work, SPH is used to simulate the soil-water jet ... -
Phase field modeling of brittle fracture in an Euler–Bernoulli beam accounting for transverse part-through cracks
Lai, Wenyu; Gao, Jian; Li, Yihuan; Arroyo Balaguer, Marino; Shen, Yongxing (2020-04-01)
Article
Accés obertWe present a phase field model to simulate brittle fracture in an initially straight Euler–Bernoulli beam, with generalization to curved beams. We start from formulating the problem with the principle of minimum potential ... -
Phase-field modeling of fracture in linear thin shells
Amiri, Fatemeh; Millán, Daniel; Shen, Yongxing; Rabczuk, Timon; Arroyo Balaguer, Marino (2014-02)
Article
Accés obertWe present a phase-field model for fracture in Kirchoff-Love thin shells using the local maximum-entropy (LME) meshfree method. Since the crack is a natural outcome of the analysis it does not require an explicit representation ... -
Simulating and interpreting Kelvin probe force microscopy images on dielectrics with boundary integral equations
Shen, Yongxing; Barnett, David M.; Pinsky, Peter M. (2008)
Article
Accés obertKelvin probe force microscopy KPFM is designed for measuring the tip-sample contact potential differences by probing the sample surface, measuring the electrostatic interaction, and adjusting a feedback circuit. However, ...
