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 ...
