... when subjected to edge-to-surface impacts ( Fig. 8 ) than the nail hammers, a result McIntire and Manning attributed to the wider chamfer and also to a more slender handle possibly making the tool more shock resistant. The tinner's-setting hammers were the least resistant to spalling, lacking any...

... fiber is noted for its toughness and general damage tolerance characteristics ( Ref 24 ). In part, this is related directly to conventional tensile toughness, or the area under the stress-strain curve. Toughness is also related to composite impact resistance and ballistic stopping power ( Ref 25 , 26...
