# Abaqus Cohesive and Gasket Elements
|
|
|
|
## Definition
|
|
|
|
Abaqus cohesive and gasket elements are special-purpose interface elements for finite-thickness or zero-thickness layers whose response is dominated by separation, compression, sealing, or interface damage.
|
|
|
|
## How They Work
|
|
|
|
Cohesive elements can use a continuum approach or a traction-separation description. They support two-dimensional, three-dimensional, axisymmetric, and pore-pressure variants, and they often work together with damage initiation and damage evolution laws.
|
|
|
|
Gasket elements represent sealing layers whose through-thickness compressive response is central. They can use material-based gasket behavior or directly specified gasket behavior, with two-dimensional, three-dimensional, and axisymmetric libraries.
|
|
|
|
## Why It Matters
|
|
|
|
These elements bridge contact, fracture, and material modeling. They are appropriate when an interface has its own constitutive thickness or degradation law, rather than being only a surface constraint.
|
|
|
|
## Connections
|
|
|
|
- [[Finite Element Contact Formulation]] covers surface-based interface alternatives.
|
|
- [[Abaqus Progressive Damage and Failure]] supplies damage evolution and element deletion context.
|
|
- [[Abaqus Fracture and Enriched Discontinuity Modeling]] is the broader crack and interface failure workflow.
|
|
- [[Abaqus Material Library and Data Definition]] supplies material behavior for cohesive or gasket response.
