Hardening Parameter Homogenization for J2 Flow with Isotropic Hardening of Steel Fiber-Reinforced Concrete Composites

Numerical modeling of the stress–strain state composite materials such as fiber-reinforced concrete is a considerable computational challenge. Even if grid with resolution all inclusions built, it will take great amount time for most powerful clusters to calculate deformations one block ideal parallelization. To solve this problem, method numerical homogenization actively used. However, when plastic are taken into account, becomes much more complicated due nonlinearity. In work, description anisotropic nature hardening material and J2 flow isotropic proposed. Here, deformation periodic arrangement in form fibers considered model problem. case, assumption made that have pure elastic properties. elasticity plasticity parameters performed on representative element. The novelty work related attempt at parameter homogenization. calculated effective used problem coarse mesh. accuracy using algorithm checked problems comparison base material. finite element implementation built FEniCS computing platform fenics-solid library.
