The position of the interface nodes is set at ____________ from the vertices
Explanation: The position of the interface nodes is set at Li/2n from the vertices, where Li is the interface length (length of the side of the triangular unit) and n an integer set to 10.
Finite element method uses the concept of shape functions in systematically developing the interpolations.
C. Can be true or false
D. Can not say
Explanation: Finite element method uses the concept of shape functions in systematically developing the interpolations.
In particular, N1+N2+N3 represent a plane at a height of one at nodes ______
D. All of the above
Explanation: Any linear combination of these shape functions also represents a plane surface. In particular, N1+N2+N3 represents a plane height of one at nodes one, two, and, three and thus it is parallel to the triangle 123.
A1 is the first area and N1 is its shape function then shape function N1= ___
Explanation: The shape functions are physically represented by area co-ordinates. A point in a triangle divides into three areas. The shape functions are precisely represented as N1=A1/A .
In the equation KQ=F, K is called as ____
A. Stiffness matrix
B. Singular stiffness matrix
C. Modified stiffness matrix
D. Uniform stiffness matrix
Explanation: The stiffness matrix represents system of linear equations that must be solved in order to ascertain an approximate solution to differential equation. The stiffness and force modifications are made to account for the boundary conditions.
Principal stresses and their directions are calculated by using ____
A. Galerkin approach
B. Rayleigh method
C. Potential energy method
D. Mohr’s circle method
Explanation: Mohr’s circle is two dimensional graphical representation of the transformation law. While considering longitudinal stresses and vertical stresses in a horizontal beam during bending.
The isoparametric representation of finite elements is defined as element geometry and displacements are represented by same set of shape functions.
C. Can be yes or no
D. Can not say
Explanation: The isoparametric representation of finite elements is defined as element geometry and displacements are represented by same set of shape functions.
