Rigid sphere dropped onto a plate
$
$ LSTC Example
$
$ Last Modified: September 4, 1997
$
$ * Part 2 - plate
$ Shells (2.5 mm thick)
$ Mild steel (with strain rate effect)
$ Constrained on all four edges
$ Connected using Tied Nodes with Failure Constraints
$
$ * Part 3 - sphere
$ Solids
$ Rigid
$ Initial Velocity: -89 mm/ms to all nodes of the sphere
$
$ * Contact: nodes (plate - 2) to surface (sphere - 3) good <== this file
$ nodes (sphere - 3) to surface (plate - 2) bad
$
$ Note: For a really good demonstration of bad contact, remove all of the
$ *CONSTRAINED_TIED_NODES_FAILURE at the end of the deck and re-run
$ with the two contact definitions pointed out above.
$
$ Units: mm, kg, ms, kN, GPa, kN-mm
