Assignment 3-2D Element Formulation Challenge

OBJECTIVE

The primary objective of this assignment is to compare two simulations with different shell element properties. The comparison would be between the one with default properties and one with the following properties:

Parameters	Comment
Ishell =24	QEPH 4 nodes shells are best combination of cost and accuracy.
Ismstr=2	Full geometric nonlinearities (default)with possible small strain formulation activation in RADIOSS Engine.
Ish3n=2	Standard 3 noded shell (C0)with modification for large rotation(default)
N=5	Number of integration points set to 5 for accuracy bending.
Ithick=1	Thickness change is taken into account for accuracy.
Iplas=1	Iterative plasticity for good accuracy.

PROCEDURES

1.change the run time to 55 ms. For that, we first need to import the solver deck file in question to RADIOSS.

For that, we need to go to File > Import > Solver Deck. This brings up the import menu. Here, we can select the file we need to import. The file would be the starter input deck file (which is the file that ends with '0000.rad').

2, change the 

Tstart">Tstart������ value to 25 and to accommodate a maximum of 60 animation steps, Tfreq">Tfreq����� can be set at 1.

3.Run the base simulation.

go to the 'Analysis' section from the bottom panel.

There, we can select RADIOSS.
