# Implicit dynamic analysis using direct integration

 A direct-integration dynamic analysis in Abaqus/Standard: must be used when nonlinear dynamic response is being studied; can be fully nonlinear (general dynamic analysis) or can be based on the modes of the linear system (subspace projection method); and can be used to study a variety of applications, including: dynamic responses requiring transient fidelity and involving minimal energy dissipation; dynamic responses involving nonlinearity, contact, and moderate energy dissipation; and quasi-static responses in which considerable energy dissipation provides stability and improved convergence behavior for determining an essentially static solution. The following topics are discussed:
