Answer: A: What do you mean by consistent and lumped mass matric
... ### Consistent mass matrix Mass matrix computed by considering mass to be distributed uniform throughout the element is known as consistent mass matrix. Consistent matrix for bar element is given by $[M] = \frac{\rho Ah_e}{2} \begin{bmatrix} 2 & 1 \\ 1& 2 \end{bmatrix}$ ### Lumped mass ...

Answer: A: Write short note on principal of minimum potential energy.
... The expression for total potential energy is given by, **π= U+H** Differentiating above equation **δπ= δU+δH** In principle of virtual work **δU=δH** **δπ = 0** Hence we can conclude that a deformable body is in equilibrium when the potential energy is having stationary value. Hence the principl ...

Answer: A: what do you mean by convergence? State the criteria for convergence
... **Convergence:** In numerical method, we get an approximate solution. In FEA, the error gets reduced by increasing the number of elements or the degree of polynomial. If the final solution obtained matches with the exact one expected, within permissible error we say convergence is reached. **Criter ...

Answer: A: Explain sources of error in FEM.
... **Sources of error in Finite Element Method** **1. Discretization error:** Its results from transforming the physical problem into a finite element model and can be related to modeling the boundary condition. These results are more prominent in 2D and 3D problems and can be reduced by increasing th ...

Answer: A: Write short note on Sub parametric, ISO-perimetric an super parametric elements
... **Isoparametric element** Generally it is very difficult to represent the curved boundaries by straight edge elements. A large number of elements may be used to obtain reasonable resemblance between original body and the assemblage. In order to overcome this drawback, isoparametric elements are use ...

Answer: A: What are the h and p versions of FEM.
... **h-method:-** More accurate information is obtained by increasing the number of elements. The name for the h-method is borrowed from mathematics. The variable h is used to specify the step size in numeric integration. If a part is modeled with a very course mesh, then the stress distribution across ...
