Assignment 3-2D Element Formulation Challenge
Aim- to study the change in energy when we change the shell properties and analyse the difference
1 import the starter file in hyperworks
2 to change the Tstop we need to go to cards and click on eng_run, and change Tstop from 60 to 55.
3 in second question we have to change the animation steps which means we ahve to change Tfreq in the card and eng_anim_dt
4 to change the shell properties you need to scrool down to the properties section click on each property and check the card image section if its a shell properties change all the recommended properties given in the question
now go to the analysis section and click on radios
save the file in a new name and click on radios
click on radios and check the folder there will be some automated fles generated in sequence which are the animation steps file
split the screen in three sections
click on the second section and upload the .h3d file from the folder in which all the autogenerated files were kept. and click on apply
click on the third section and select hypergraph2d as the type
upload the t01 file from the folder of animation steps files.
analyse the result

QUESTION 8----
GRAPHICALLY REPRESENTATION
TOTAL ENERGY--
BEFORE EDITTING TOTAL ENERGY DECREASES WITH TIME
AFTER EDITTING TOTAL ENERGY REMAINS CONSTANT THROUGH OUT THE PROCESS
HOURGLASS ENERGY--
BEFORE EDITTING HOURGLASS ENERGY INCREASES WITH TIME
AFTER EDITTING HOURGLASS REMAINS ZERO
CONTACT ENERGY--
BEFORE EDITTING CONTACT ENERGY VARY WITH TIME
AFTER EDITTING CONTACT ENERGY REMAINS CONSTANTLY ZERO
INTERNAL ENERGY--
BEFORE EDITTING INTERNAL ENERGY INCREASE WITH TIME
AFTER EDITTING INTERNAL ENERGY INCREASE WITH TIME
QUESTION 9----DIFFERENCE BETWEEN BOTH OF THEM IS ONLY BECAUSE OF THE HOURGLASS ENERGY AS QEPH REDUCES THE HOURGLASS ERROR AND IT SHOWS QEPH GIVES BETTER RESULTS. AS WE ALL KNOW HIGH HOURGLASSING ENERGY IS OFTEN A SIGN THAT MESH ISSUES MAY NEED TO BE ADDRESSED.
