Fracture formation in vitrified thin films of cryoprotectants
If the elastic modulus had been different (since E = 1 GPa was merely a guess), the stress would have changed nearly in proportion. However, the ratio of the stress at fracture to the elastic modulus, also defined as the fracture strain, is essentially independent of the choice of elastic modulus value.

May 26, 2017· Scratch tests were performed to study failure mechanisms in TiAlN coatings deposited on substrates from steel 12Cr18Ni9Ti. It is shown that coating failure begins with crack generation at the apices of pile-ups formed along the scratch due to plastic ploughing of the substrate material. With further increase in indentation load the failure process is governed by the competition between tensile ...
