Week 1 Stress Concentration on a Plate with hole

OBJECTIVE:

1. TO DETERMINE THE MAXIMUM STRESS AND DEFORMATION DEVELOPED BY THE MODEL IN TWO DIFFERENT CASES.

CASE 1:

1. 300*120*30 RECTANGE WITH 60MM DIA IN THE CENTER

CASE 2:

1. SAME PLATE WHICH HAS ADDITIONAL TWO HOLES WITH THE DIA OF 30MM FROM 90MM DISTANCE FROM THE CENTER TO THE BOTH SIDES.

DEFORMATION AND STRESS RESULTS:

CASE 1:

1. FOR THE CASE 1 (PLATE WITH ONE HOLE) THE MAX DEFORMATION IS 0.00024432mm FOR THE 500N LOAD TOWARDS OUTSIDE (POSITIVE Z DIRECTION)

2. THE MAX STRESS IS 0.59148Mpa AT THE TOP AND BOTTOM OF THE CIRCLE.

CASE 2:

1. FOR THE CASE 2 (PLATE WITH MULTIPLE HOLES)THE MAX DEFORMATION IS 0.00029711mm FOR THE 500N LOAD TOWARDS INSIDE (NEGATIVE Z DIRECTION)

2. THE MAX STRESS IS 0.56462Mpa AT THE TOP AND BOTTOM OF THE CIRCLE.

POINT OF VIEW:

1. FROM THE ANALYSIS POINT OF VIEW I CHOOSE CASE 2 (THE PLATE WITH 3 HOLES). BECAUSE THE STRESS IS UNIFORMLY DISTRIBUTING WHILE APPLYING LOAD. IN THE FIRST CASE THERE IS MORE CHANCES ARE AVAILABLE FOR THE BREAKING VERY SHORT TIME BECAUSE THE LOAD IS ACTING MAJORLY AT THE PARTICULAR AREA(TOP AND BOTTOM SIDE OF THE CIRCLE)

2. FROM THE MANUFACTURING POINT OF VIEW I PREFER FOR THE EASY OPERATION CASE 1(PLATE WITH ONE HOLE). BECAUSE THE MANPOWER AND WORKING TIME WILL BE MORE LESS.

IN THE WEIGHT REDUCTION CASE, I CHOOSE CASE 2(PLATE WITH MULTIPLE HOLES). BECAUSE THE WEIGHT IS REDUCED BY THE ADDITIONAL TWO HOLES.

REPORT:

1. FIRST I OPENED WORKBENCH AND DRAG AND DROP STATIC STRUCTURAL FROM THE LEFT COLUMN.

2. THEN I CHOOSE MY MATERIAL AS STRUCTURAL STEEL.

3. THEN I OPEND SPACE CLAIM FOR THE GEOMETRY.

4. AFTER COMPLETED DEISGN I CLOSE THE SPACE CLAIM AND I OPENED THE MECHANICAL GUI. AND UPDATE MY GEOMETRY.

5.THEN UPDATE MY MATERIAL AND FIX THE COORDINATE SYSTEMS AS WELL.

6. FOLLOWED BY I CHOOSE THE MESHING SIZE AND METHODS AND FINAlIZE THE MESH.

7. THEN I GAVE THE BOUNDARY CONDITIONS FIXED SUPPORT AND LOADS AS WELL.

8. THEN I GAVE THE RESULT SUGGESSIONS AS TOTAL DEFORMATION ANS TOTAL STRESS.

9. THEN RUN THE ANALYSIS AND I GOT THE RESULTS. I HAVE ATTECHED THE RESULT ALONG WITH THIS REPORT.
