Case Studies and Workbooks

From time to time, NAFEMS publishes reports giving detailed information about finite element analyses in the form of Case Studies and Workbooks. Those published so far are detailed below.

R0019 ,   Pickering , A N, and Ricketts, D C,   NAFEMS Workbook of Examples, circa 1990.

This gives 10 worked examples, to enable a newcomer to finite element analysis to follow. The geometries are kept simple to minimise data generation effort. Explicit input details are given, and various resulting aspects are highlighted and discussed. The workbook is aimed to complement those who have recently completed the NAFEMS recommended 30 hour training course.

R0086 ,   NAFEMS,   Advanced Workbook of Examples and Case Studies (Volume 2), 2003.

R0008 ,   White, P S, and Lowe, M J S,   Case Studies in Non-Linear Analysis, 1990.

Two very detailed descriptions of case studies in non-linear analysis are given. The first involves a geometrically complex component that is subjected to a repeated cycle of mechanical and thermal loading. Several analyses of varying complexity were involved, some including plasticity and creep. The second case is a benchmark exercise involving the calculation of thermal, elastic and creep response of rock salt. Again, complex non-linear behaviour was followed using thermal transient analysis and creep. Both studies are very specialised, but are still relevant as rather complicated benchmarks with a strong educational element.
