Transcript

  • 1. Structural Analysis And DesignProgram
    Developed by
    Bentley Systems
  • 2. “What” Is Analysis?
    Calculation of the response of structures to
    actions
  • 3. “Why” to perform an Analysis
    To calculate
    Stress distribution
    Natural frequencies
    Displacement
    Critical Buckling loads.
  • 4. Methods of Engineering Analysis
    • Experimental Method
    Example: Prototype model
    • Analytical method or Theoretical Analysis
    Using Mathematical Differential equations
    • Numerical method
    Finite element method*
  • 5. Basic TerminologiesStructural analysis
    Stress
    Strain
    Poisson ratio
    Hook's law
    Young's modulus
    Bending moment
    Shear force
    Stress strain curve for various materials
    Linear
    Nonlinear
    Isotropic vs. anisotropic vs. orthotropic
  • 6. Basic TerminologiesStructural analysis
    Structure
    Beam
    Column
    Truss
  • 7. Introduction to FEM & FEA
    FEM-Finite element method
    FEA –Finite element analysis
  • 8. FEM
    Finite element method of structural analysis was created by academic and industrial researches during 1959’s and 1960’s
    Theoretical approach.
    Examples
    Euler's rule, LaGrange method,
    Newton raphson method, Fourier series
  • 9. Nature of FEM
    Force method (Forces unknown)
    Strain energy method
    Consistent deformation method
    Matrix flexibility method
    Clayperons theorem of 3 moments
    Displacement method (Displacements unknown)
    Kanis method
    Slope deflection method
    Matrix stiffness method
    Moment distribution method
    FEM
  • 10. FEA
    FEA-
    simulate loading conditions on design & determine design response to these conditions
    The design is modeled using discrete elements called elements
    The sum of response of all elements in the model gives the response of design
  • 11. Problem types in FEA
    Boundary value problem-static and steady state analysis
    Initial value problem-fluid flow
    Eigen value problem-Modal analysis, vibration and natural frequency
    Boundary initial value problem-forced vibration, transient and dynamic analysis
  • 12. FEM
    Nodes
    Elements
    Types of elements
    1D-Line element(Min 2 nodes)
    2D-Plane element (Area-Min 4 node)
    3D-Solid element (Volume-min 8 nodes)
  • 13. Stages
    Preprocessor
    Solution
    Postprocessor
  • 14. Meshing
    Process of discritization of a structure into element and nodes
    Infinite no of D.O.F to Finite D.O.F
    Types of discritization
    Natural
    Artificial
  • 15. Basic terminologies meshing
    Aspect ratio
    Skewing
    Warp age
    Types of refinement
    H refinement
    P refinement
  • 16. Meshing-Importance & drawbacks
    Why should we mesh
    Element quality
    Problems associated with meshing

  • 18. Static analysis
    Analysis of a structure for various loads under static condition i.e. component under rest when loads are applied
    Examples
    Holding devices-Clamp or fixture analysis
    Types
    Linear analysis
    Non linear analysis
  • 19. Dynamic analysis
    Analysis of a structure for various loads under Dynamic condition i.e. component is in motion when loads are applied or time varying loads
    Examples
    Suspension systems of a vehicle
    Types
    Linear analysis
    Non linear analysis
