Reverse Engineering Ants for Robotics

Submitted by Simpleware on

New research is emerging out of a project where Ohio State University used our software to reconstruct the anatomy of an ant neck. In this project, micro-CT scans of an ant neck were reconstructed using Simpleware software and exported as a mesh for analysis in Abaqus.

How to model discrete mass-spring system in ABAQUS?

Submitted by Tingge Xu on

Hi everyone,

 

I am currently working on a project which needs mass-spring model. Previously I use MATLAB to implement 1D and 2D system, and I want to model 3D system by ABAQUS now. I am just starting to learn ABAQUS, it seems like there is not much tutorial or example about this kind of model.

 

Using XFEM in Abaqus to Model Fracture and Crack Propagation

Submitted by SIMULIA on

Join us on this FREE one hour eSeminar. Register below for the live seminar in your time zone.

Engineers are under increasing pressure to improve and extend the operating life of structural components. Abaqus FEA provides proven robust capabilities for modeling bulk fracture and crack propagation in composites.

This live eSeminar will focus on basic concepts of extended Finite Element Method (XFEM) in Abaqus, damage modeling and the creation of an XFEM fracture model. There will also be a short hands-on demonstration using Abaqus 6.13.

ABAQUS Reinforced Concrete Beam Model

Hi All,



I am trying to model a simply supported reinforced concrete beam with longitudinal reinforcement. I am using 8-node solid elements for the concrete, and 2-node truss elements for the longitudinal reinforcement bars. I have embedded the reinforcement bars in the concrete using an Embedded Region constraint. I am then applying a displacement at the midspan (deflection control). I am using the Concrete Damaged Plasticity model for the concrete. My model begins to run but will not converge. Some of the error messages that I get are:
