The Hilber-Hughes-Taylor (HHT) α-method. Objective: introduce damping in the Newmark method without degrading the order of accuracy. (). 1. 2. 2. 1. 1. 1. Create a Hilber-Hughes-Taylor (HHT) integrator. This is an implicit method that allows for energy dissipation and second order accuracy (which is not possible. Two unconditionally stable implicit methods with controllable numerical dissipation are compared, namely the improved version of the.

Simulations using the proposed algorithm of an engine model, a model with contacts, and a emthod with flexible bodies indicate a 2 to 3 speedup factor when compared against benchmark MSC. Like Mewmark and all the implicit schemes, the unconditional stability of this method applies to linear problems. Depending on choices of input parameters, the method can be unconditionally stable. Beam With Hinges Element 1. Elastic-No Tension Material 1. Shibboleth is an nethod management service that provides single sign-on protected resources.
This is an implicit method that allows for energy dissipation and second order accuracy which is not possible with the regular Newmark object. Wide Flange Section 1.
