It might not seem like scraping the top of a cold stick of butter with a knife could be a scientific test, but engineers say the process is very similar to the "scratch test," which is perhaps the ...

Fracture toughness is a critical measure of a material's ability to resist crack propagation in the presence of pre-existing flaws. Resistance curve (J–R curve) analysis, employing parameters such as ...

Adhesives in bonded parts are frequently subjected to varying degrees of direct and indirect strain. The capacity of adhesives to endure such strains is crucial to ensure bonds remain reliable and ...
