Problem 1_ CST Elements in FEM _ Finite elements methods

[@yashshrivastava2079]

3:54 how did you make those 9 expression of alpha beta gama 1,2,3 ?

[@bsuneel9863]

Aera of triangle is 10

[@good.future.academy]

Area is equal to 10 not 20.1

[@ankitshinde2997]

Right bro

[@isaacamornorteyyowetu]

Thanks for this working example. I think N1=0.4, N2=-0.1 and N3=0.7. Then N1+N2+N3=1

[@MaheshGadwantikar]

Yes, it should be 1

[@swapneilraj5242]

how did you calculated alpha,beta and gamma values ????

[@allhindisongs9606]

we can do direct
N1=sai N2=Nita and N3=1-sai-nita
x=N1*x1+N2*x2+N3*x3
y=N1*y1+N2*y2+N3*y3
two unknown two equations

[@jarapalarayudu6669]

hi sir can u do the problem on rectrangular element with the help of gaussian quadrature integration .....

[@MaheshGadwantikar]

Okay

[@S_B_CREATION555]

N1=0.4 , N2=-0.1, N3=0.7 values

[@MaheshGadwantikar]

Some of the Shape function should be equal to Zero

[@at9595]

Derive an expression for shape function of a triangular linear element.
Same question hai kya Sir??

[@MaheshGadwantikar]

No

[@at9595]

@@MaheshGadwantikar Sir iska derivation bta denge please 🙏🙏

[@adityasawant6021]

Thank you so much sir 😊

[@MaheshGadwantikar]

🙏🙏

[@pavankumaryt5420]

area of triangle is 10mm square

[@MaheshGadwantikar]

Okay

[@shubhrasparsh912]

@@MaheshGadwantikar ok

[@abhishekrathi851]

Sir A ka maan 20.1 kese aaya mere 10 aa rha hai

[@MaheshGadwantikar]

Calculate the area by using the formula, You should make determinant while calculating A

[@menkapandey482]

Can you share numerical of shape function

[@MaheshGadwantikar]

Okay I will

[@bsuneel9863]

N1=0.4,N2=0.7,N3=-0.10
Then we get sum of N1,N2,N3=1

[@MaheshGadwantikar]

It should be One only

[@Manashorts-s]

Then what about Point P (4, 6)

[@omkar5067]

Thank you bro

[@MaheshGadwantikar]

💕💕🙏

[@realstarrs9023]

Tq soo much sir.

[@ravindramishra9354]

Agar p given na ho to

[@aryaprabhatsingh1735]

Area of Triangular Element is 10 sir.

[@ankitshinde2997]

Sir area is 10

[@anirudhkuntilla]

ans is wrong bro
the sum of shape functions should be equal to 1 u r getting 1.2

[@MaheshGadwantikar]

Yes. Ur right , Sum of shape function should be equal to one.

[@LETSDISCUSS1]

Area shall be corrected. As he write it down just looking at somewhere ,

[@good.future.academy]

Det is wrong

[@S_B_CREATION555]

A=10

[@adityachikane8477]

the answers are come wrong by this method go by textbook method only

[@atchutarao584]

Wrong... Don't upload such wrong stuff
