This paper focuses on some of the most notable changes to the Trilinos project in the last few years.Abstract:
Since An Overview of the Trilinos Project [ACM Trans. Math. Softw. 313 2005, 397--423] was published in 2005, Trilinos has grown significantly. It now supports the development of a broad collection of libraries for scalable computational science and engineering applications, and a full-featured software infrastructure for rigorous lean/agile software engineering. This growth has created significant opportunities and challenges. This paper focuses on some of the most notable changes to the Trilinos project in the last few years.At the time of the writing of this article, the current release version of Trilinos was 10.12.2.read more

Coupled phase-field and plasticity modeling of geological materials: From brittle fracture to ductile flow
TL;DR: In this paper, the authors derive a phase-field formulation for fracture in elastic-plastic materials as a balance law of microforce, in a new way that honors the dissipative nature of the fracturing processes.

Stabilized mixed finite elements for deformable porous media with double porosity
Jinhyun Choo,Ronaldo I. Borja +1 more
TL;DR: In this article, a finite element framework for coupled solid deformation and fluid diffusion in double porosity media was developed, which employs a thermodynamically consistent effective stress, and mixed finite elements that interpolate the solid displacement and pore pressures in the macropores and micropores were used for this purpose.
Journal ArticleDOI
Hydromechanical Modeling of Unsaturated Flow in Double Porosity Media
TL;DR: In this article, a thermodynamically consistent framework for hydromechanical modeling of unsaturated flow in double-porosity media is developed, where conservation laws are formulated incorporating an effective stress tensor that is energy-conjugate to the rate of deformation tensor of the solid matrix.

Computational thermo-hydro-mechanics for multiphase freezing and thawing porous media in the finite deformation range
SeonHong Na,WaiChing Sun +1 more
TL;DR: In this paper, a stabilized thermo-hydro-mechanical (THM) finite element model is introduced to investigate the freeze-thaw action of frozen porous media in the finite deformation range.

Cracking and damage from crystallization in pores: Coupled chemo-hydro-mechanics and phase-field modeling
TL;DR: In this paper, a theoretical and computational framework for modeling these crystallization-induced deformation and fracture in fluid-infiltrated porous materials was developed, where conservation laws were formulated for coupled chemo-hydro-mechanical processes in a multiphase material composed of the solid matrix, liquid solution, gas, and crystals.
