also there is one more question for the elemental stress we can divide the quadrilateral in two CST and do it for each since it is not curved surface

[@udayjordan4262]

it will be extra work i guess because[B] we are already finding the strain disp matrix we will be using it to find the element stress directly

[@themechanicalengineer]

Yes of course! But the purpose is to learn everything

[@udayjordan4262]

the values for {u} are given less there should be 8 values there are only 6 values

[@themechanicalengineer]

Yes, the last two were zero; that was a typo error.

How to multiply 3*4 with 4*8 matrix

[@themechanicalengineer]

We can't use calculator for this purpose... The only way is to go with the manual calculation...

[@ShravanKumar-jb5ie]

Pls tell me how to do manually

[@themechanicalengineer]

Watch this video - kzbin.info/www/bejne/ZpbJmGWCgr2bq6M . Instead of 3*3 & 3*3, in our case its 3*4 & 4*8... The procedure is same...

tq sir

[@g.sinstitution42]

Sir what is 'D' in this

[@themechanicalengineer]

D is strain displacement Matrix

From day of exam 😢

[@themechanicalengineer]

Do well! All the best 😁
