摘要:

ABSTRACTThis paper pursues the conclusion, reached in earlier papers2that the details of glass fissures can be explained on the basis that the head of an advancing fissure cndeavors at all times to stay at right angles to the principal tension in its immediate neighborhood. This argument is followed here into some of its more complex manifestations, particularly into the complications of fissure‐form that arise when the fissure‐front splits, giving rise to hackle‐texture and “stries” (“feather‐patterns”) on the one hand and to radiant formati

摘要:

ABSTRACTThis paper straightens out the physical homogeneity of the impact formula used by several American writers on this subject, shows the probable derivation of the formula, and proposes, by taking the square root of the formula, to reduce it to comprehensibility.

摘要:

ABSTRACTThis paper attempts to analyze results provided by Dr. Guyer and Mr. Shenvood, with a view to finding out if anything useful is being obtained from impact testing figures beyond what is gotten from static tests. It is shown that in general, with the aid of the rationalization proposed in the foregoing paper, the impact and static tests can be compared as a simple ratio, and that this ratio has a pronounced tendency to be constant for given conditions of testing.

摘要:

ABSTRACTSince the polariscopic evidence as to the strains in wire glass caused by the wire is either absent or hard to interpret, this paper was originally a mathematical investigation as to what strains there ought to be, and what they ought to look like in the polariscope. In the present pages, however, the findings are presented first in nonmathematical form, and the mathematical skeleton is secreted in a cupboard or appendix. The findings arc checked with the polariscopic evidence, and a number of interesting points are, it is believed, here presented for the first time.
