lämpöshokkimakestävyyttä
Lämpöshokkimak refers to a phenomenon observed in certain materials, particularly ceramics and glass, where rapid changes in temperature can cause them to fracture or break. This occurs due to uneven expansion and contraction of the material. When a material is heated rapidly, the outer layers expand faster than the inner layers. This differential expansion creates stress within the material. Conversely, rapid cooling causes the outer layers to contract more quickly than the inner layers, again inducing stress. If the thermal stress exceeds the material's tensile strength, it will lead to cracks or complete breakage.
The susceptibility of a material to thermal shock depends on several factors, including its thermal conductivity,
To minimize the risk of thermal shock, materials can be heated and cooled slowly and uniformly. For
