of samples according to the four-point loading scheme.
During cyclic testing
, a continuous sequence of compression and extension loadings having the same intensity was regularly applied to simulate dynamic conditions, which was seen from the steady change of q/[[sigma]'.sub.0] between +0.20 and -0.20.
The testing jig design and configuration was based upon earlier work.23 A regular platform 3.75 mm diameter Nobel Biocare implant laboratory analogue (Nobel Biocare AB, Box 5190, 40226 Goteborg, Sweden) was cemented into the endofanacrylicrod that was held in a plastic block attached to the base of a cyclic testing
machine (Model HC 10, Dartec Limited, Stour bridge, West Midlands, DY 98 SH, UK).
Listed below are cyclic testing
results for eight systems:
A similar behavior was also observed during cyclic testing
in the textured AZ31 sheet .
An important result from the material testing found no evidence of significant reduction in composite liner adhesion properties of lap shear or peel strength due to field aging after over a decade and subsequent to 100 years of additional field-simulated mechanical aging cyclic testing
The texture analyzer either operates in compression or tension modes where cyclic testing
may be applied within each.

Zwick's Proline and Allround electro-mechanical testing machines can be used for a wide range of tests including tensile, compressive, bend, peel, tear, shear and cyclic testing
"We are pleased to say that despite a tight schedule to work with, which involved an intensive smoke and toxicity and cyclic testing
campaign, the suite has outperformed expectations in the areas of reliability and efficiency.
