• Experimental strain analysis using brittle lacquer is very effective and reliable, because it can detect fully the higher stressed regions over the surface to be inspected. There are two types of brittle lacquer, which are baking and air drying. Air drying type is generally more insensitive than baking one. However, even in case of the latter the brittleness decreases rapidly with the increase of heat capacity which is proportional to the mass of machines and structures to be inspected. Therefore, cracking does not easily occur over the coated surface. Refrigeration method using water has been practised to improve the sensitivity, but this method is inaccurate on account of thermal stress on the coating induced by quenching. To cope with this obstacle, the author has developed an advanced method applying solvent-cracking as follows. In case the coating using Calcium-Rosin as basic ingredient comes into contact with solvent, coating comes to show "solvent-cracking" which is peculiar to high polymers, and thus the cracking of coating occurrs at a lower stress than that in air. Several medium which decrease the "cracking-resistance" have been found. They are polar solvents such as 1, 4-butanediol, ethylene glycol and others which are easily available. For machines and structures having large heat capacity, experimental strain analysis using brittle lacquer had been very difficult so far, but by applying this new method, the failure in experiment can be eliminated.
