Several static stress analysis procedures are available in
Abaqus/Standard:
- Static analysis
-
Static stress analysis
is used for stable problems and can include linear or nonlinear response.
- Eigenvalue buckling
analysis
-
Eigenvalue buckling prediction
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
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
is used to analyze the transient response of structures considering
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
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.
- Low-cycle fatigue
analysis
-
Low-cycle fatigue analysis using the direct cyclic approach
is used to predict progressive damage and failure for ductile bulk materials
and/or to predict delamination/debonding growth at the interfaces in laminated
composites based on the direct cyclic approach in conjunction with the damage
extrapolation technique.
