55 // Description: This file contains the class definition for DistributedDisplacementControl.
56 // DistributedDisplacementControl is an algorithmic class for perfroming a static analysis
57 // using the arc length scheme, that is within a load step the follwing
58 // constraint is enforced:
59 // i=1 delta U^T delta U + alpha^2 delta lambda^2 = delta s^2
60 // i>1 dU^T delta U + alpha^2 dLambda delta lambda = 0
61 // where dU is change in nodal displacements for step, dLambda is
62 // change in applied load and DistributedDisplacementControl is a control parameter.
63 //
