... testing is covered in ASTM D 790 (three-point loading) and ASTM D 6272 (four-point loading). The specimen length is dependent on the thickness. A span-to-thickness ratio of 16 to 1 is recommended if the ratio of tensile strength to shear strength is less than eight to one. The span-to-thickness must...

... Shear Stress-Strain Adhesive bond strength is usually measured by the simple single-lap shear test shown in Fig. 17.22 . The lap shear strength is reported as the failing stress in the adhesive, which is calculated by dividing the failing load by the bond area. Because the stress distribution...

.... An example of test data at two solids levels is given in Fig. 5.18 for aluminum nitride powder (48 and 50 vol%) in a wax-polymer binder at 140 or 160 °C (285 or 320 °F). This log-log plot shows viscosity versus shear strain rate. Both the solids loading and shear-rate effects are evident; compare 48 and 50...
