    • Fourth order phase-field model for local max-ent approximants applied to crack propagation 

      Amiri, Fatemeh; Millán, Daniel; Arroyo Balaguer, Marino; Silani, Mohammad; Rabczuk, Timon (2016-12)
      Article
      Open Access
      We apply a fourth order phase-field model for fracture based on local maximum entropy (LME) approximants. The higher order continuity of the meshfree LME approximants allows to directly solve the fourth order phase-field ...

    • Phase-field modeling of fracture in linear thin shells 

      Amiri, Fatemeh; Millán, Daniel; Shen, Yongxing; Rabczuk, Timon; Arroyo Balaguer, Marino (2014-02)
      Article
      Open Access
      We 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 ...

    • XLME interpolants, a seamless bridge between XFEM and enriched meshless methods 

      Amiri, Fatemeh; Anitescu, C; Arroyo Balaguer, Marino; Bordas, S P A; Rabczuk, Timon (2014-01)
      Article
      Open Access
      In this paper, we develop a method based on local maximum entropy shape functions together with enrichment functions used in partition of unity methods to discretize problems in linear elastic fracture mechanics. We obtain ...
