本研究主要是利用有限元素分析軟體ANSYS，來模擬並探討雷射加工玻璃時所造成移除效果及產生的溫度場和所引發的應力場。由軟體計算出的數值結果，與先前已做出的實驗結果來進行比對，驗證其真確性。在本文中，我們以熱傳學的基本熱傳理論應用至雷射加工的技術上，藉以探討玻璃的熱傳情形，以及所會產生的相關物理變化。再者我們藉由文獻中的轉換公式，將ANSYS程式所計算出的溫度場分布，藉由溫度梯度會產生應力變化的理論，轉換為應力場的分布情形。由模擬之結果，我們可以發現工件之最高溫度為1959 K。移除率為208.93μm。最大應力為2.09×10^8 Pa。再者，我們研究試著改變製程參數，如水輔助加工方式，探討其對於我們所關心的在玻璃表面的溫度場及應力場變化情形及對加工品質的影響。在此狀況下，我們發現工件之最高溫度為1665 K。移除率為166.93μm。最大應力為1.72×10^8 Pa。較在空氣中為低。本文主要是提供有意進行新一代雷射加工玻璃量產化研究的學術與技術人員，一個減少實驗成本及最佳化製程技術的有效方法。

The goal of this research is to use the commercial finite element software; the ANSYS, to analysis the temperature and stress field on the surface of the glass. By applying the basic heat conduction theory on laser technology, we discuss the heat transfer phenomena and physical behavior change of the glass. And we use the thermal stress equation to convert the temperature field data into equivalent stress field data. By this method we managed to calculate the maximum temperature is 1959 K and the maximum stress is 2.09×10^8 Pa when glass is processing in air. When the glass processing in water, the maximum temperature change to 1665 K and the maximum stress became to 1.72×10^8 Pa, it is much lower than processing in air. With this simulation method, we can let researcher to reduce the cost of real experiment and improve the efficiency of developing the new types of mass process method of glass by using laser.
