Advanced Static finite element Analysis

Brief outline : It is  said that all  the  practical  problems are nonlinear  whereas  linear static is  the first  level of approximation in engg. Analysis . This course starts with  the limitations of  linear  static finite element  analysis . When we should carry out  Nonlinear FEA  and  detailed discussion  on  types of nonlinearities are  followed  by   Practical  examples and applications .Classification  of problems , strain and stress measures  in nonlinear analysis ,  Solution methodologies . Inertia Relief  , Submodeling and  Superelement  analysis are also  introduced . Practical  Project Work  . HYPERMESH  for FE Modeling and  FEA  with  MSC- NASTRAN  are the tools that we  use  for the course . 
Eligibility :  Enginnering /Diploma in Mechanical , Production ,Automobile , Civil ,Chemical and other branches or  experienced candidates.
Prerequisite :  Finite Element Modeling and Basic FEA  Course.
Contents :  Background review of  Linear static analysis in MSC NASTRAN . Geometric , material and boundary /contact nonlinearities in nature .  How do we characterize them , When to go  for Nonlinear  Finite Element analysis . True Strain and Stress and other strain and stress measures in  Nonlinear Finite element analysis . converting Engineering Stress-Strain Curve to  True StressStrain . Contact as an ON-OFF Switch , Newton Raphson  and other solution methodologies .How to solve  inertia relief problems through support entries , submodeling as a practical tool to solve stress analysis problems , superelement analysis .Direct and iterative solvers , Practical  tutorials and  project work  .
