Operations systematically to obtain displacements, necessarily satisfying (Southwell 1935a and 6): that is to say, we calculate exactly the effects ofĬertain prescribed displacements, or “ operations”, and we combine these “ relaxation method” previously employed in relation to frameworks The second method we believe to be new and likely to be specially However if we check the 1937 paper by Southwell, he cites his older paper on relaxation methods and apparently it is unrelated to the current usage in solving linear equations iteratively and this clearly not the first usage. Householder The Theory of Matrices in Numerical Analysis (1964, p. The Deflexion of Beams under Transverse Loading," Proceedings of the Royal Society of London A, 161, (1937), 155-181. Southwell "Relaxation Methods Applied to Engineering Problems. RELAXATION, as a term in numerical analysis for a particular method of successive approximation, derives from Southwell’s work, beginning with K. In the iterative methods for solving a system of linear equations, a term called relaxation method is often appears along with Jacobi and Gauss Seidel methods.
