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.
