18MEL66 Computer Aided Modelling and Analysis Lab syllabus for ME

Course Learning Objectives:

• To acquire basic understanding of Modeling and Analysis software
• To understand the concepts of different kinds of loading on bars, trusses and beams, and analyze the results pertaining to various parameters like stresses and deformations.
• To lean to apply the basic principles to carry out dynamic analysis to know the natural frequencies of different kind of beams.

Experiments

PART A

1 Study of a FEA package and modeling and stress analysis of:

a. Bars of constant cross section area, tapered cross section area and stepped bar

b. Trusses – (Minimum 2 exercises of different types)

c. Beams – Simply supported, cantilever, beams with point load , UDL, beams with varying load etc. (Minimum 6 exercises)

d. Stress analysis of a rectangular plate with a circular hole.

PART B

2 Thermal Analysis – 1D & 2D problem with conduction and convection boundary conditions (Minimum 4 exercises of different types )

3 Dynamic Analysis to find:

a) Natural frequency of beam with fixed – fixed end condition

b) Response of beam with fixed – fixed end conditions subjected to forcing function

c) Response of Bar subjected to forcing functions PART C(only for demo)

4 a. Demonstrate the use of graphics standards (IGES, STEP etc) to import the model from modeler to solver.

b. Demonstrate one example of contact analysis to learn the procedure to carry out contact analysis.

c. Demonstrate at least two different types of example to model and analyze bars or plates made from composite material.

Course Outcomes:

At the end of the course, the student will be able to:

CO1: Use the modern tools to formulate the problem, create geometry, descritize, apply boundary conditions to solve problems of bars, truss, beams, and plate to find stresses with different-loading conditions.

CO2: Demonstrate the ability to obtain deflection of beams subjected to point, uniformly distributed and varying loads and use the available results to draw shear force and bending moment diagrams.

CO3: Analyze and solve 1D and 2D heat transfer conduction and convection problems with different boundary conditions.

CO4: Carry out dynamic analysis and finding natural frequencies of beams, plates, and bars for various boundary conditions and also carry out dynamic analysis with forcing functions.
