Subspace-based explicit dynamic analysis: The subspace projection method in ABAQUS/Standard uses direct, explicit integration of the dynamic equations of equilibrium written in terms of a vector space spanned by a number of eigenvectors (“Implicit dynamic analysis using direct integration,” Section 6.3.2). The eigenmodes of the system ...

The explicit dynamics analysis procedure is based upon the implementation of an explicit integration rule together with the use of diagonal (“lumped”) element mass matrices. The equations of motion for the body are integrated using the explicit central-difference integration rule

Acces PDF Abaqus Tutorial Dynamic Analysis use Abaqus(R) software in order to apply the Finite Element Method to variety of civil engineering problems. The readers may find this book fundamentally different from the conventional Finite Element Method textbooks in a way that it is written as a Problem-Based Learning (PBL) publication.

Defining a dynamic analysis in Abaqus/Standard Optional parameter for the subspace projection method SUBSPACE Include this parameter to choose the subspace projection method (explicit integration of the model projected onto the eigenvectors obtained in the last FREQUENCY step preceding this step).

In ABAQUS/Standard dynamic studies of linear problems are generally performed by using the eigenmodes of the system as a basis for calculating the response. In ...

General nonlinear dynamic analysis in Abaqus/Standard uses implicit time integration to calculate the transient dynamic or quasi-static response of a system.

Furthermore, if the displacement or velocity histories have nonzero initial values, Abaqus/Standard will make corrections to the initial accelerations as described in Modal dynamic analysis. The default is to give an acceleration history for mechanical degrees of freedom and to give a displacement for an acoustic pressure. Input File Usage

Abaqus/Explicit uses the central-difference operator. In an implicit dynamic analysis the integration operator matrix must be inverted and a set of nonlinear equilibrium equations must be solved at each time increment. In an explicit dynamic analysis displacements and velocities (applicable to structural

General nonlinear dynamic analysis in Abaqus/Standard uses implicit time integration to calculate the transient dynamic or quasi-static response of a system. The procedure can be applied to a broad range of applications calling for varying numerical solution strategies, such as the amount of numerical damping required to obtain convergence and the way in which the automatic time incrementation ...

The explicit dynamics procedure performs a large number of small time increments efficiently. An explicit central-difference time integration rule is used; each increment is relatively inexpensive (compared to the direct-integration dynamic analysis procedure available in Abaqus/Standard) because there is no solution for a set of simultaneous equations.
