Assignment 3-2D Element Formulation Challenge

OBJECTIVE:-

To Run The Simulation of crash beam file with run time of 55ms and to limit animation files within 25 to 50
To Assign required shell element properties and then again run simulation
To Plot Graphs of Hour glass energy,Internal Energy,Kinetic Energy and Total Translational Energy also to plot Rigid Wall
To Plot Graphs For no propeties condition and with properties conditions

WHAT WILL I LEARN?

This Exercise drives us through performing simulations by running Radioss solver also here shell element properties are going to be assigned to give the clear verification of elements and also we'll understand Graphs regarding Hourglass Energy,Internal and Kinetic energy and also rigid wall forces.

PROCEDURE:-

Here Procedure for Crash Beam File Is Classified Into 2 Steps i.e Run Without Properties and Run With Properties

CASE 1 :- RUN WITHOUT PROPERTIES:-

Import the Radioss file with rad 00 and import in Hypermesh Window with Default Radioss Solver.
Assign 55seconds as time and frequency 1.22 we get 39 Animation files since animation files should be in the range of 25 to 50
Click on Analysis and save the file in a folder that you created enter options as -nt 4 and run the Simulation.
Click on Radioss To Run the simulation and observe the deformation occuring in the model.
Open the Window of Hyperview and import h3d file and choose options from preferences tab and click onto visualisation mode and make 1D elements dotted with 0.15mm so that it can be viewed and different contour options can be performed.
Make Sure to check Energy error and mass error energy error has to be negative in range if its positive then it should be under 15%
Split The Window in Half and make the other half window to Hypergraph Mode here we can plot the graphs.
Click on Global Variables then Click on INTERNAL ENERGY,KINETIC ENERGY,HOURGLASS ENERGY and TOTAL TRANSLATIONAL ENERGY.
Delete previous entities and create new plot to upload Rigid Wall Configuration and Click on Normal Force ,Tangent Force And Total Resultant.
Move onto Hyperview window and create the Vonmises stress analysis with Averaging method as simple and click on measures window to determine the Dynamic Min MaxResult to get the result displayed.
You Can view the simulation parallely in Hyperview and Hypergraph by importing template file.

EXPLAINATION OF GRAPHS:-

To Explain The Energy Graphs Internal energy was intially low and it increases because of the deformation that is causing within
Kinetic Energy Gradually Reduces since it starts with max energy which leads it to the deformation and due to impact kE Gradually decreases.
Hour glass energy Slightly increases
Total translational Energy is relatively in a linear format but with slight deviation with energy embedded in the body and few shifted due to impact.
To Explain The Rigid Wall Simulation insert normal force and Tangent force since Tangent force acts as friction force also insert total resultant.
Normal force and resultant mostly collide such that majority of the force is acting along the normal direction of the beam.
Normal force intially is very high due to high kinetic energy and decreases eventually because of reducing its energy due to impact.
Tangent Force is minimum and eventually increases due to reduced kinetic energy and friction was minimum at start due to increase in friction Energy has been reduced
