Hilber-hughes-taylor method
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 ...

WebTherefore, the well-known trapezoidal rule (TR), also denominated Newmark’s constant average acceleration method , the backward differentiation formula (BDF) , the generalized-α method [12,13], and the Hilber–Hughes–Taylor-α method (HHT-α) have been employed in the solutions of DAEs. WebJun 1, 1992 · The Hilber-Hughes-Taylor (HHT) α-method is applied to the direct integration of the equations of conduction heat transfer. The method is shown to possess improved algorithmic dissipation, relative to the general trapezoidal methods, while retaining second order accuracy.
