Thermo shock
Webb熱衝擊（英語： Thermal shock ） ，指熱輻射使物體受到局部快速加熱。 結果是，由於物體各部溫度升高速度不同，膨脹程度也不同，故其內部產生應變和應力，有些應力可超過脆性固體的強度，而使它斷裂。 熱膨脹係數大的玻璃器皿，局部受熱而破裂是一典型例子。. 熱衝擊使物體所產生應力差別大 ... Webb4 nov. 2024 · Thermal shock tests were performed at three different nominal peak flux levels: 30 W/cm 2, 40 W/cm 2, and 55 W/cm 2 with a total of five identical samples tested at each flux. The sample location for all tests was approximately 950 mm from the lamps along the optical axis.
