应变场（strain field）是指应变状态的空间函数，也即应变状态随空间点的变化。物体受外力或其他因素影响时，它内部的应变呈现某种分布状况。为了表明物体的这种情况，将物体连同它内部的应变分布状况称为应变场。通常用主应变轨迹线来表示。

Although welding temperature field and stress, strain field are bi-directional couple, because stress and strain field have little influence on temperature field, this paper only considers the single couple which temperature field effects on stress and strain field.
虽然焊接温度场与应力应变场是双向耦合的，由于应力应变场对温度场的影响非常小，加上计算条件的限制，所以本文只考虑温度场对应力应变场的影响这一单向耦合。
