= Guyan reduction
{wiki=Guyan_reduction}
Guyan reduction, also known as the Guyan method or Guyan condensation, is a mathematical technique used in structural dynamics and finite element analysis to reduce the size of a model while retaining its essential dynamic characteristics. It was developed by the engineer Robert H. Guyan in the 1960s. The method is particularly useful for simplifying large structural models containing many degrees of freedom, making them easier to analyze and compute.
