Shape function in finite element analysis
Webb29 aug. 2013 · Shape Functions or Interpolation Functions. In FEA we discretize the solution region into finite elements. To conduct the analysis we assume a displacement … Webb4 nov. 2024 · Alternatively, FEM and other numerical methods are meant to provide an engineering analysis that takes into account much greater detail—something that would be impractical with hand calculations. FEM divides the body into smaller pieces, enforcing continuity of displacements along these element boundaries.
