Sample ME6603 Question Bank:
1. What is essential boundary condition?
Primary boundary condition or EBC Boundary condition which in terms of field variable is known as Primary boundary condition.
2. Natural boundary conditions?
Secondary boundary natural boundary conditions which are in the differential form of field variable is known as secondary boundary condition
3. How do you define two dimensional elements?
Two dimensional elements are define by three or more nodes in a two dimensional plane. The basic element useful for two dimensional analysis is the triangular element.
4. What is CST element?
Three noded triangular elements are known as CST. It has six unknown displacement degrees of freedom (u1, v1, u2, v2, u3, v3). The element is called CST because it has a constant strain throughout it.
5. What is LST element?
Six nodded triangular elements are known as LST. It has twelve unknown displacement degrees of freedom. The displacement function for the elements are quadratic instead of linear as in the CST.
6. What is QST element?
Ten nodded triangular elements are known as Quadratic strain triangle. It is also called as cubic displacement triangle.
7. What meant by plane stress analysis?
Plane stress is defined to be a state of stress in which the normal stress and shear stress directed perpendicular to the plane are assumed to be zero.
8. State the principles of virtual energy?
A body is in equilibrium if the internal virtual work equals the external virtual work for the every kinematically admissible displacement field.
