Need guidance on understanding Finite element analysis to the core. I mean i want to have full command over finite element analysis. i can ask silly question , that type of guidance is required. 7004663485
please put all your queries here. I shall try to answer. There are many others on this platform.
Dear Gourav Sinha, see attached a very good textbook for beginners in FEM. I have used this book during my Finite Element Methods coursework at the School of Mechanical, Industrial and Aeronautical Engineering at Wits University.
The Finite Element Method: A Practical Course

Armand Augustin Fondjo thanks a lot for your guidance. Sir actually i am working on isogeometric analysis. for which FEM is necessary. And i want it to implement it through MATLAb. So if possible , guide me ,
Thanks a lot for your guidance
Armand Augustin Fondjo i want to apply 3 noded rectangular element in classical plate theory. How to merge classical plate theory equation and finite element modelling ?? plz help me
Dear Gaurav Sinha, This is reply from my side from what I did many years ago. Classical plate theory has equations in terms of x,y (i.e you eliminate z variation). The idea is to look at the strain equations.
In FEM, one has to look at the degrees of freedom at the nodes (per node). So then one needs to select the number of nodes such that variation inside the element captures the equation for the plate (in terms of the strain ). You may focus on a single element. Then you find the total degrees of freedom for the element (in local coordinate system).
May be you know some of it already.
Dear Arun Agrawal sir, I have gone through J n reddy book on FEA. The things i understood the cpt theory, element used(12 terms or 16 terms), but what i dint get is that how they have merged equation of cpt and the shape fucntions to get element stiffness matrices and mass matrices
Dear Gourav Sinha, This is the main part and you will get in few rounds. JN Reddy' book is not a good introduction in my opinion, and rather an advanced text. Please check the book (or course material) referred by Prof AA Fondjo. Some textbook is essential, course material is even better. Please keep posting.
Arun Agrawal Sir i have been reading that book also , there was very much less given on plates. Can you suggest me some books or course material
Arun Agrawal, Armand Augustin Fondjo, I got stuck mainly on how to impose given boundary conditions on the Finite element model of thin plates
Dear Gourav Sinha.
See below the link of one of my article on modelling plate use FEA. Please send me your e-mail in case. Thanks
