WebOct 12, 2024 · It also relies on the Hilber–Hughes–Taylor time integration method. Moreover, three different damping algorithms are employed in this program to study the nonlinear response of Koyna dam. It is concluded that variable damping algorithms leads to a more localized crack pattern in comparison to constant damping algorithm alternative. WebThe Hilber-Hughes-Taylor operator is an extension of the Newmark β-method. Numerical parameters associated with the Hilber-Hughes-Taylor operator are tuned differently for moderate dissipation and transient fidelity applications (as discussed later in this section).
