Finite element simulation of dislocation field movement
Computer Assisted Methods in Engineering and Science, 2023 The problem of dislocation motion in monocrystals is faced in the framework of the continuum theory of dislocations. The presented approach is based on the defects balance law. A constitutive model is formulated which relates the driving forces with the

Unified Framework for Finite Element Assembly
, 2009 At the heart of any finite element simulation is the assembly of matrices and vectors from discrete variational forms. We propose a general interface between problem-specific and general-purpose components of finite element programs.

Three-Dimensional Explicit Finite Element Simulation of Piled-Raft Foundation
Journal of Engineering, 2020 This paper aims to validate a proposed finite element model to be adopted in predicting displacement and soil stresses of a piled-raft foundation. The proposed model adopts the solid element to simulate the raft, piles, and soil mass.
