Weband the HHT method of Hilber, Hughes & Taylor (1977). The Newmark method with its commonly used values (γ=2β=0.5) is the most accurate unconditionally stable scheme (Dahlquist, 1963), but results in excessive numerical oscillations. Introduction of numerical dissipation into the Newmark scheme damps the spurious oscillations, but the method ...

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). WebA new family of unconditionally stable one-step methods for the direct integration of the equations of structural dynamics is introduced and is shown to possess improved algorithmic damping properties which can be continuously controlled.
