在实驗应力分析中,涂漆法是常用的最簡单的方法之一。在零件的表面涂上一层薄薄的脆性漆,当零件受力时,漆层上即出現裂紋,用它研究零件最大应力的区域和确定主变形方向最为有效,同时也可估計应力的大小。涂漆法下适用于在液体中工作的零件的应力分析。以松香、氢氧化鋇为主要原料,以二硫化碳为溶剂的脆性漆常在下列范围内应用:溫度8℃—35℃,湿度到90％,被研究的零件其弹性变形不应小于3·10~(-2)％,
In the experimental stress analysis, paint method is one of the most commonly used method. A thin layer of brittle paint is applied to the surface of the part. Crazing occurs on the paint when the part is subjected to force. It is most effective to use it to study the maximum stress area of a part and to determine the direction of main deformation, and to estimate the magnitude of stress . Under the paint method is suitable for stress analysis of parts working in liquid. To rosin, barium hydroxide as the main raw material, carbon disulfide as a solvent brittle paint often in the following range of applications: temperature 8 ℃ -35 ℃, humidity to 90% of the parts under study its elastic deformation should not be less than 3.10 ~ (-2)%,
