the crack morphology of transgranular stress corrosion cracking (tgscc) suggests that the mechanism of growth and the condition at which tgscc occur is different than that of intergranular stress corrosion cracking (igscc). several attempts have been made to characterize igscc probabilistically; however, limited effort has been noticed for tgscc.

in petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. the rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts.
sharp cracking sounds were lightning, coming and going in staccato waves. rolling rumbles were thunder, and a deeper note still was the song of seabed - hugging currents that circled the world. he
