摘要
The present invention comprises an experimental assessment method and a series of test tubes having special slots with different responses to fragile destruction, depending on the radius r1 located on the originating point of the slot (the remaining parameters of the test tubes pertaining to this series are constant). The purpose of the present invention is to experimentally obtain the value of the parameters srfr and II of each structural material, which are unknown since three hundred years. Manufacturing processes must be highly accurate including high quality materials so that good quality experimental results are obtained. Nowadays, the aforementioned information is useful for correcting current software, which would otherwise not evaluate correctly the resistance of materials and structures acting under Three-dimensional Stress Field conditions, which is highly dangerous for humanity and individuals.
