Definition: Embriostability, also known as embrittlement or damage to a material by repeated exposure to stress or heat, is an irreversible process that occurs when a substance undergoes changes in its structure due to external forces. This can lead to increased susceptibility to deformation and failure over time. The term "embrittlement" comes from the Greek word "embrios," which means "bacteria," as it was used by ancient Greek philosophers to describe the growth of bacteria on rocks or other materials
