FEM and Modal Analysis in Engineering
December 24 - December 28
Objectives of the Course:
Exposing the participants to need of computational approach and scope of FEM solutions. Fundamental implementation concepts in FEM, weighted residual methods/ weak form formulations, application in engineering problems. Explore non -linear FEM, solution methodology by non – linear FEM and case study of practical engineering problems that arise in different domain namely structural analysis, fluid flow, heat transfer, vibrations, etc. Finite Element Method (FEM) is the most powerful method for the analysis of engineering problems. It is capable of handling geometry complicated domains, a variety of boundary conditions, non-linearity and coupled phenomenon those are common in real life problems. The physical knowledge of method enhances the analysis skill and provides a greater understanding of the problems being solves. Commercial software packages based on the finite element method are often used in industrial, research and academic institutions for the solution of engineering and scientific problems related to solid mechanics, fluid mechanics, heat transfer, and structural dynamics. The intelligent use of these software packages and correct interpretation of the output is often predicted on knowledge of the basic concept of FEM. Modal analysis is the study of the dynamic properties of structures under vibrational excitation. The main aim of modal analysis in structural mechanics is to determine the natural frequencies, mode shapes and damping coefficients of a structure during free vibrations. It is common to use the FEM to perform this analysis because the structure being analyzed can have arbitrary shape and the results of the calculations are acceptable. It is also possible to test a physical structure to determine its natural frequencies and mode shapes. This is called an Experimental Modal Analysis. The results of the physical test can be used to calibrate a finite element model to determine if the underlying assumptions made were correct (for example, correct material properties and boundary conditions were used). This course will be particularly beneficial for engineering students, engineers and scientists working in various institutions. At the end of the course, participants may be in position to identify and select appropriate finite element methodologies for specific conditions.
