Abstract

In this research, the embedded element method is investigated as a method for creating a finite element model for fiber reinforced composites. Bundles of polyethylene fibers are represented by truss elements and embedded in a continuum element matrix material by tying the displacement of the two meshes together. This type of mesh can be created more quickly than layered models while still maintaining directional layers than can capture the indirect tension mechanism that is important to compression failure[1–4]. Here, we show that by varying the number of fibers represented by a single truss element, the size of the finite element model can be scaled up or down for macro or micro scale modeling without changing the material properties or modeling method being used.
