WebMar 2, 2024 · Dynamic relaxation is an iterative method to solve nonlinear systems of equations, which is frequently used for form finding and analysis of structures that undergo large displacements. It is based on the solution of a fictitious dynamic problem where the vibrations of the structure are traced by means of a time integration scheme until a static … Dynamic relaxation is a numerical method, which, among other things, can be used to do "form-finding" for cable and fabric structures. The aim is to find a geometry where all forces are in equilibrium. In the past this was done by direct modelling, using hanging chains and weights (see Gaudi), or by … See more Considering Newton's second law of motion (force is mass multiplied by acceleration) in the $${\displaystyle x}$$ direction at the $${\displaystyle i}$$ node at time $${\displaystyle t}$$: See more • A S Day, An introduction to dynamic relaxation.

WebJul 6, 2024 · Dynamic relaxation (DR) is the most widely used approach for static equilibrium analyses. Specifically, DR compels dynamic systems to converge to a static equilibrium through the addition of fictitious damping. DR methods are classified by the method in which fictitious damping is applied. Conventional DR methods use a fictitious … WebCompared with the stiffnessdirect -analysis approach, the dynamic relaxation method (DR) is a more time-efficient alternative for the analysis of structural systems with material and geometrical nonlinearities. This method, introduced by Otter [21] and Day [22] in the mid-1960s, is based on an explicit iterative method for the static solution ...
