tips for the reader

hello reader 

            i want to tell you few tips to not waste the time in vacations.

 1. search for a job.

2. plan for your next sem.

3. collect the information about your syllabi for the next semister.

4. try to do something creatively using the resources you have.

5. try to explore the more efficient ways of utilizing the available resources[computer, calculator,...etc.

6.what we learn in our lie is definitely helps us in any one form in our life.

7. dont let your skills to vanish.

8 roam the streets of your city . 

9. think about the previous semister and analyse yourself write down the positives and negatives from it. implement the positives and also try alternatives for the negatives.

ansys procedure for a plate with hole.

PART B

Stress analysis of a rectangular plate with a circular hole

**** For 2D and 3D problems, after the geometry has been created meshing is to be done

(elements/ nodes are created) ****

Problem 1. In the plate with a hole under plane stress, find deformed shape of the hole and

determine the maximum stress distribution alond A-B (you may use t = 1 mm). E = 210GPa,

t = 1 mm, Poisson’s ratio = 0.3, Dia of the circle = 10 mm, Analysis assumption – plane stress

with thickness is used.

Step 1: Ansys Utility Menu

File – clear and start new – do not read file – ok – yes.

Step 2: Ansys Main Menu – Preferences

select – STRUCTURAL - ok

Step 3: Preprocessor

Element type – Add/Edit/Delete – Add – Solid – Quad 4 node – 42 – ok – option – element

behavior K3 – Plane stress with thickness – ok – close.

Real constants – Add – ok – real constant set no – 1 – Thickness – 1 – ok.

Material Properties – material models – Structural – Linear – Elastic – Isotropic – EX – 2.1e5 –

PRXY – 0.3 – ok – close.

Step 4: Preprocessor
Modeling – Create – Area – Rectangle – by dimensions – X1, X2, Y1, Y2 – 0, 60, 0, 40 – ok.
Create – Area – Circle – solid circle – X, Y, radius – 30, 20, 5 – ok.
Operate – Booleans – Subtract – Areas – pick area which is not to be deleted (rectangle) – apply
– pick area which is to be deleted (circle) – ok.
Meshing – Mesh Tool – Mesh Areas – Quad – Free – Mesh – pick all – ok. Mesh Tool – Refine
– pick all – Level of refinement – 3 – ok.
Step 5: Preprocessor
Loads – Define loads – apply – Structural – Displacement – on Nodes – select box – drag the left
side of the area – apply – DOFs to be constrained – ALL DOF – ok.
Loads – Define loads – apply – Structural – Force/Moment – on Nodes – select box – drag the
right side of the area – apply – direction of For/Mom – FX – Force/Moment value – 2000 (+ve
value) – ok.
Step 6: Solution
Solve – current LS – ok (Solution is done is displayed) – close.
Step 7: General Post Processor
Plot Results – Deformed Shape – def+undeformed – ok.
Plot results – contour plot – Element solu – Stress – Von Mises Stress – ok (the stress
distribution diagram will be displayed).
Step 8: PlotCtrls – Animate – Deformed shape – def+undeformed-ok
