Significant bending can be induced due to misalignment sstm the adherends, resulting in premature failure. Need more than one copy? Standards Subsctiption may be the perfect solution.

Specimens may be designed with either a circular or square cross-section. It is difficult to envisage using the butt joint for assessing long-term performance of adhesive joints under combined cyclic and hostile environments, considering the difficulties associated with this configuration inc.

ASTM D Standard: Tensile Strength Tester for Adhesives by Means of Bar and Rod Specimens
In the absence of this restraint, the adhesive is free to undergo radial contraction with respect to the stiffer adherend. Historical Version s – view atsm versions of standard. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D Qualitative adhesive property data only Strain measurements difficult High shear and peel stresses at bondline asgm 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 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.
The average strength is taken as the applied load at failure divided by the bond area. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. This analysis assumes that the adhesive has a much lower stiffness than the adherends i.

As the voice of the U. Rounding the adherend butt edges to a diameter equal to the adhesive thickness can facilitate their removal. We are confident that we have what you are looking for.
An alternative test method for determining the tensile strength of adhesives is Test Method D This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations.
In marked contrast, the stress state in the outer edges is highly complex, varying through the thickness of the adhesive layer. Circular cross-section specimens are usually used to facilitate manufacture and maintain symmetry.
This 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 ]. The stress state at the overlap edges i. Transfer of load to an adhesively bonded structure by tension, either directly or indirectly peelrepresents the most severe form of d20955, since the strength of the joint relies on the tensile strength of wstm adhesive, which is low.
