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
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)
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
