Matrix structural analysis using finite elements

摘要: Although simple finite elements as truss members and beam in frames have been used structural analysis for many years, the general element methods of developped only recently parallel with development digital computers. It is use matrix high speed computers that makes feasible. At present time are being extensively design flight vehicle structures well other types structures. Many large purpose computer programs specialized developed These various usually calculate assemble matrices by one three described previous chapters. Most displacement method analysis; a few force mixed method, while some more than method.
