In particular, the effect of disc thickness, test rig diameter, loading ball diameter, load spreader under ball and finally rig design on the measured biaxial strengths for alumina and glass were considered.
The coatings, which were 20 28 μm in thickness, were tested under low velocity impact (33 m s− 1) in an air sand erosion rig and the damage features were studied in order to determine the erosion mechanisms.
Thirteen circular RC slabs with dimensions of (1200 mm in diameter and 75 mm in thickness) were tested under repeated loading through annular load subjected at the center of slabs.
Loops have been observed in sand-cast material in a variety of tempers under tension or compression, and in high-pressure die-cast material with different cross-section thickness tested in tension.
The minimum stress needed to destroy the integrity of the shell was extracted and found to be smaller than or close to that of silica hollow particles with different shell thickness tested in the literature.
The technique also provides strong evidence of a difference in cake structure through destructive thickness testing, despite cake thicknesses being almost equivalent.
Two prototypes, 0.6 mm and 0.8 mm in thickness, were repeatedly tested on fractured sheep mandibles, fixed in a purpose-built jig, to loads up to 150% of the maximum forces developed by human patients.
