Numerical simulation of dolos drop tests

Abstract A three-dimensional finite element method (FEM) analysis is conducted to simulate dolos drop tests. The FEM analysis employs a nonlinear concrete material model and utilizes a contact surface at the base of the vertical fluke. The results of the analysis predict the dynamic states of stress in the dolos and the pattern of cracking in the unit.
