Transfer of load to an adhesively bonded structure by tension, either d0295 or indirectly peelrepresents the most severe form of loading, since the strength of the joint relies on the tensile strength of the adhesive, which is low.

The stress state at the overlap edges i. Tensile stresses are virtually impossible to avoid, however there is a need for reliable test methods to measure the tensile properties asym the adhesive. The tensile stresses in the central region of the adhesive layer for butt tension specimens are uniformly distributed and there are no shear stresses present [ 6—7 ].

The spew is able to transmit some of the applied load, resulting in a significant reduction in the level of axial stresses within the adhesive joint, and thus contributing to the uncertainty in moduli and strength data. A small misalignment can severely reduce strength data. Already Subscribed to this document. Qualitative adhesive property data only Strain measurements difficult High shear and peel stresses at bondline edges Strength sensitive to spew fillet Sensitive to specimen misalignment Limited to thick and rigid adherends Failure attributed to peel stresses Special bonding fixture required.

The presence of the adherends has the effect of inducing radial and circumferential stresses, thereby increasing the effective stiffness of the joint. An alternative test method for determining the tensile strength of adhesives is Test Method D The average strength is taken as the applied load at failure divided by the bond area. This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

A further consideration, relates to the removal of the spew fillet i.

We are confident that we have what you are looking for.

Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. This analysis assumes that the adhesive has a much lower stiffness than the adherends i. The adhesive in the bondline is restrained in the radial and circumferential directions by the adherends.

This standard is also available to be included in Standards Subscriptions. It is good design practice, therefore, to ensure that the load is transferred by shear or compression and that direct or induced tensile stresses are minimised. This standard is not included in any packages. The test is difficult to perform. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D The reader should refer to the ISO standards relating to the testing of polymeric materials [ 12 ].

Large, indefinable, stress concentrations at the periphery of the adhesive layer can be expected to render the strength data meaningless. Please first verify your email before subscribing to alerts. D205 effectively increases the bondline thickness at the outer edges of the bondline, and as a result non-linear stress effects may result, especially at elevated temperatures and exposure to high humidity environments [ 6—7 ].
