And the critical specimen width, sheet thickness and tensile-shear strength were all linearly increased with weld length.
Then the relationship between the weld length and critical specimen sizes, including specimen width and sheet thickness, was investigated through analyzing the failure modes in tensile-shear testing using statistical method.
The strain in these sub-regions deviates significantly from the global applied strain for regions smaller than 18 mean cell diameters, indicating a critical specimen size, below which certain bulk properties are no longer representative.
For a ductile material, such as mild steel or aluminum, after the initial period of elastic deformation, the same critical point the specimen's limit of elastic deformability is reached.
Leona A. Doyle and Andrew M. Bellizzi: collection of pathology specimens, critical revision of manuscript.
For SEM, critical point-dried specimens were coated with gold in a Bal-Tec SCD 005 cool sputter coating system (Leica Microsystems).
There is considerable debate on the reliability of the subspecific status so identified [ 11, 13, 14], since morphological characters are readily influenced by regional climatic and habitat variation, and identification of subspecies has often been based on locality rather than critical examination of specimens [ 5].
However, fibre length is more critical for the specimen geometry studied in the ± 45° and 90° directions and this effectiveness is much lower (approximately 70%).
The critical energy for specimen perforation did not vary with the mass of the impactor, i.e. strain rate, in the range investigated.
In the core part of this study, sixteen (16) shear-critical RC beam specimens were tested under three-point loading for assessing the effect of FRCM stiffness/type, FRCM configuration, and FRCM anchorage on the load and deformational capacities of the strengthened beams.
