What Is ASTM D2293 Adhesive Shear Creep Compression?
ASTM D2293 is the standard test method for the creep of structural adhesives under a constant compressive shear force. Testing adhesive joints under continuous stress to assess long-term deformation provides key information on performance and durability over extended periods.
This test applies to many adhesives used to bond metals, plastics, and composites, especially in load-bearing roles where long-term reliability is crucial. By watching deformation unfold over extended periods, ASTM D2293 helps predict service life under real-world operating conditions.
Applications and Benefits of ASTM D2293 Adhesive Shear Creep Compression Testing
Scope
ASTM D2293 outlines procedures for measuring shear creep deformation in adhesives subjected to constant compressive loading.
It evaluates:
- Time-dependent shear deformation
- Creep compliance and strain rate
- Long-term load-bearing capability

Our ASTM D2293 Testing Procedure
Specimen Preparation
Bonded specimens are prepared in overlapped or butt-joint configurations with cleaned, treated surfaces and controlled curing.
1Alignment & Setup
Specimens are carefully aligned to ensure uniform shear stress development during loading.
2Compression Loading & Deformation Measurement
A constant compressive load is applied, and shear deformation is measured at defined time intervals.
3Environmental Conditioning
Testing may be performed at ambient or elevated temperature and humidity to simulate service conditions.

ASTM D2293 Adhesive Shear Creep Compression FAQs
ASTM D2293 is used to measure the time-dependent deformation (creep) of adhesives when subjected to constant shear stress under compression loading.
Creep behavior determines whether an adhesive can maintain joint integrity over long periods, especially in structural and load-bearing applications.
Mainly structural adhesives, including epoxies, acrylics, and polyurethane systems used in aerospace, automotive, and construction industries.
