  • Finite Element Stress Analysis of Engineering Structures/Aircraft Components
    The finite element analysis course is aimed at solving real life design problems. Students will be more exposed to problems related to aero-structures. This course gives special attention in simulating the structure more realistically. In this course the important aspects of structural design are addressed.

    The course is as follows:

  • Representation of multiple load path structure more realistically in finite element modeling
  • Identifying maximum stress location from which a failure will initiate
  • Better understanding of the response of the structure for a given loading scenario
  • Developing finite element models for fatigue analysis
  • Solving fracture mechanics problems using Finite element analysis
  • Finite element analysis of airframe components
  • Finite element analysis of airframe structural joints
  • Design of principal structural elements through Finite element analysis to retain the stress-strain response around the critical location of the airframe

  • The course:

  • Importing/Generation of geometric model
  • Meshing using standard Pre-processing software package
  • Preparation of the model for carrying out the analysis
  • Post-processing of the analysis results
  • Verification of results

  • Types of Analysis:

  • Linear static analysis
  • Buckling analysis
  • Composite structural analysis
  • Introduction to fatigue calculations using analysis results
  • Introduction to non linear analysis
  • Introduction to thermal analysis

  • Software packages used:

  • MSC-PATRAN
  • MSC-NASTRAN

  • A Project work will be given at the end of the course. This will include hands on experience on all the stages of pre & post processing of the structural model. Verification of FEA response of the structure for a given set of loads & boundary conditions with Strength of Material (SOM) calculations
