Explicit Impact Simulation of Concrete Confined With a Network of Rebar Steel

Explicit Impact Simulation of Concrete Confined With a Network of Rebar Steel

In this project, a network of steel rebar was considered as concrete reinforcement in order to improve its energy absorption capacity under impact of a rigid body.

 

The FE model was generated in Hypermesh and run in LS-Dyna with explicit solution.

One of the main goal of the analysis was to find crack distribution under impact area which is depicted in following pictures. So Mat_Winfrith_Concrete (*MAT084-085) were used that that had ability to generate additional binary output database containing information on crack location.

Different number of rows of 0deg and 90deg steel network were used and impact velocity was 4m/s.

About Me


I have been doing simulation support on variety of projects within automotive and aerospace industries as well as on civil projects since 2004. Regarding my CAE skills using LS-Dyna, ANSYS, Altair Hyperworks and ADAMS I am well able to perform simulations on the following areas:
  • Crashworhiness, Pedestrian
  • Static & Dynamic and Coupled-Field
  • Friction Stir Welding (FSW)
  • Multi-body Dynamic

Please contact me if you need technical support in your projects by sending your request to mehrmashhadi@gmail.com
