A static stress procedure is one in which inertia effects are neglected. Several static stress analysis procedures are available in ABAQUS/Standard:
Static analysis: Static stress analysis, Section 6.2.2, is used for stable problems and can include linear or nonlinear response.
Eigenvalue buckling analysis: Eigenvalue buckling prediction, Section 6.2.3, is used to estimate the critical (bifurcation) load of “stiff” structures. It is a linear perturbation procedure.
Unstable collapse and postbuckling analysis: Unstable collapse and postbuckling analysis, Section 6.2.4, is used to estimate the unstable, geometrically nonlinear collapse of a structure. The method can also be helpful in obtaining a solution in other types of unstable problems, and it is often suitable for limit load analyses.
Quasi-static analysis: Quasi-static analysis, Section 6.2.5, is used to analyze transient response to time-dependent material behavior (creep and swelling, viscoelasticity, and viscoplasticity). A quasi-static analysis can be linear or nonlinear.
Direct cyclic analysis: Direct cyclic analysis, Section 6.2.6, is used to calculate the stabilized cyclic response of the structure directly. It uses a combination of Fourier series and time integration of the nonlinear material behavior to obtain the stabilized cyclic solution iteratively.
