An associated implicit integration scheme, which can handle complex separation paths and mixed-mode fracture, is developed, and the implicit CZM is implemented in an implicit solver via a user subroutine, for structural analysis. The constant interface parameters are identified from a thermodynamic ...
the integration scheme is particularly important in critical large deformation solutions, see e.g. [6,12–14]. Since the publication of the time integration scheme for finite element solutions involving nonlinear large deformations, much additional experience has been gained. As may be expected, ...
The proposed method for solving the above equation of motion is first introduced through a modification of an explicit integration scheme for a single-degree-of-freedom system. The extension of this approach to multi-degree-of-freedom systems will be discussed later. In an explicit integration proc...
In the present work a new implicit time integration scheme for arbitrary loading conditions is presented ensuring accurate simulation results. Within this scheme special focus is on the evolution of the stress field between two successive discrete crack fronts of the incremental procedure. By the ...
First 3D time dependent numerical simulations of natural convection in liquid metals with the semi-implicit time integration schemes confirm the theoretically estimated gain in the time step width and result in CPU-time savings up to a factor of 50 compared to the fully explicit scheme. Page %P ...
In doing so, the explicit integration scheme unavoidably includes inertial effects, and hence this scheme is good for transient dynamic analysis. The acceleration obtained is then used to acquire the displacement by using methods such as the central difference method. Because the global stiffness ...
A comprehensive study of the two sub-steps composite implicit time integration scheme for the structural dynamics is presented in this paper. A framework is proposed for the convergence accuracy analysis of the generalized composite scheme. The local truncation errors of the acceleration, velocity and...

However, if a cell is cut, we use a space-tree integration scheme. Since the diagonality of the element mass matrix is lost on cut elements, we prefer to utilize the more accurate Gauß-Legendre quadrature on the space-tree integration mesh. The element stiffness matrices and the load ...
