Using build-in Impact Pre-processor

Exercise 1a: Rectangular plate under pressure

A rectangular plate (thickness 1mm) is loaded with an increasing pressure from 0 to 0.002 GPa in 1 ms. The plate is made of steel. The modulus of elasticity 210 GPa, Poisson's ratio 0.3, Yield stress 0.18 GPa and the elastic-plastic modulus 0.1. The edges of the plate are all fixed. The simulation of the plate under pressure is observed in 1 ms.


Using GiD to Impact Interface

You have to install GiD, then GiD to Impact interface can be integrated to GiD.

GiD to Impact interface can be found in Impact folder (/interfaces).

  • Download the latest version of Impact then unzip it
  • Go to unzipped Impact directory and find a folder "interfaces"
  • Copy a folder "impact.gid"
  • Find the directory where you install GID (In Windows normally under C:/program files) and open the folder.
  • Find a folder "problemtypes"
  • Paste the folder "impact.gid" to the folder "problemtypes". Done!

To activate GiD to Impact interface, from GiD menu Data, click Problem types then select Impact.

Exercise 2a: Cantilever Plate

An impactor hits vertically at the tip of a cantilever Aluminium 2024-T3 plate (100mm x 50mm thickness of 2 mm) fixed at one end. The impactor has a constant velocity of 3 m/s. Simulation time: 15 ms.


Exercise 2b: Colliding cylinders

A steel cylinder (1 mm thickness, radius 20 mm, length 200 mm) is fixed in both ends. Another cylinder (the same geometry and material) in 90 deg orientation is colliding the fixed-end cylinder. The motion of cylinder is in the direction of x-axis with the velocity of 10 m/s. Simulation time: 20 ms.
