The **heat deflection temperature** or heat distortion **temperature** (HDT, HDTUL, or DTUL) is the **temperature** at which a polymer or plastic sample deforms under a specified load. This property of a given plastic material is applied in many aspects of product design, engineering and manufacture of products using thermoplastic components Determination. The heat distortion **Stress Due to Temperature Change**::Fundamentals As can be seen from the above table, **aluminum** has larger value than steel. This means that, subjected to the same **temperature** variations, **aluminum** structures undergo larger changes in volume than similar steel structures. If the structure is prevented from movements (restrained) while subjected to a **temperature** change, stresses will develop.**Thermal Bending Analysis** Further Details (For **temperature** increases, **deflection** occurs toward the side of lower thermal expansion.) Therefore, there are 4 possible deformed configurations: Notice that in all of these cases, if we assume that the deformation at the edges completely defines the deformation within the interior of the PWB, the total PWB **deflection** is the sum of the
