DOI: 10.1002/nme.6500
Abstract: Energy‐conserving integrations are widely used in long‐time simulations of mechanical systems because they exhibit excellent stability and conserve the discrete energy in conservative systems. However, in many applications, their errors of other quantities, for example,… read more here.

DOI: 10.1007/s10915-020-01245-6
Abstract: A key issue in developing efficient numerical schemes for nonlinear wave equations is the energy-conserving. Most existing schemes of the energy-conserving are fully implicit and the schemes require an extra iteration at each time step… read more here.
