Prestressed modal analysis of non uniform beam using ansys

Istiyaq , M and Agarwal, A (2014) Prestressed modal analysis of non uniform beam using ansys. BTech thesis.



Beams are widely used structural members and its dynamic characteristics under loading is of great importance and vital for study. Thus, the purpose of the present thesis paper is to carry out an efficient and accurate simulation for prestressed modal analysis of non-uniform beam using Ansys. Geometric non-linearity is also considered. Displacement and frequencies of cantilever beam are studied with distributed as well as point load. The result thus obtained was verified with the result as obtained as the output of the programme in other literature survey. Chapter 1 include general introduction about the topic and related research in non-linearity in vibration of beams. Chapter 2 deals in literature review by help of which this work has been completed with satisfactory result. The theoretical background of the topic including the use of beam, relevant pre-stressed condition and its modal analysis is discussed in chapter 3.The methodology adopted is given in chapter 4.Chapter 5 deals with step by step Procedure in Ansys. Chapter 6 sums up the work with result and conclusion. Some of the publications that were referred are mentioned in Chapter 7.
