How does a quadrilateral finite element differ from a rectangular finite element ?
Answers
Answer:
The bilinear quadrilateral element is a two- dimensional finite element with both ... It is a generalization of the 4-node rectangular element.
Answer:
The quadratic quadrilateral element, also known as the Q8 element is a type of element used in finite element analysis which is used to approximate in a 2D domain the exact solution to a given differential equation. It is a two-dimensional finite element with both local and global coordinates.
the difference between linear and quadratic shape functions
The quad element refers to quadratic shape function and it means as when between 2 points this type of element has been used deformation along the edge follows a quadratic function(ax^2+Bx+c). On the other hand the linear shape function will result in a linear deformation(ax+b) along element.
