Contribution

It introduces a simulation approach to evaluate the impact of fiber deployment patterns on granular material strength and failure, providing new deployment strategies.

Findings

Different deployment patterns significantly influence failure envelopes.

Optimized deployment strategies can improve structural stability.

Simulation results guide practical fiber placement in granular columns.

Abstract

The mechanical behavior of continuous fiber reinforced granular columns is simulated by means of a Discrete Element Model. Spherical particles are randomly deposited simultaneously with a wire, that is deployed following different patterns inside of a flexible cylinder for triaxial compression testing. We quantify the effect of three different fiber deployment patterns on the failure envelope, represented by Mohr-Coulomb cones, and derive suggestions for improved deployment strategies.
