Assignment 3-2D Element Formulation Challenge

OBJECTIVE : (1) CASE 1 - RUN THE GIVEN -0000.RAD FILE IN RADIOUS AS IT IS.

(2) CASE 2 - RUN THE -000.RAD FILE AFTER MAKING RECOMMENDED CHANGES IN THE ELEMENT PROPERTY.

PROCEDURE: CASE 1- (A) FIRSTLY I DOWNLOAD THE 0000.RAD FILE AND 0001.RAD FILE AND CHANGE RUN TIME TO 55 AND TIME STEP TO 2 TO GET 26 TO 27 TIME STEPS AS RECOMMENDED IN THE ASSIGNMENT.

(B) THEN WANT TO ANALYSIS RADIOUS SELECTED LOCATIONS FOR EXTRACTION OF THE RESULT FILE AND CLICK ON RADIOUS

CASE 2 - AFTER MODIFICATION OF PROPERTY OF ELEMENTS OF RAIL

CONCLUSION : (1) HOURGLASS EFFECT IS LARGE DEFORMATION IN AN ELEMENT WITHOUT ANY STRESS THUS REDUCING THE ACCURACY AND TRUE RESPONSE OF THE STRUCTURE LRAD TO INCORRECT RESULTS. IN UNDER-INTEGRATION ELEMENTS IF THE SUMMATION OF ALL THE FORCES AT THE INTEGRATION POINT IS ZERO THEN THE ELEMENT FAIL TO CALCULATE STIFFNESS FOR THE MODE OF FAILURE THUS DEFORMATION HAPPENS IN A WIRED MANNER.

(2) IN OUR STUDY WE HAVE CHOSEN REDUCED INTEGRATION 2D SHELL ELEMENT QEPS HAVING I-SHELL EQUAL 24.
