A crack surface displacement of four-point-bendspecimen under three types of loading is studied in this paper.
研究了四点弯曲型试件在各种类型载荷作用下的裂纹面位移，并考虑了裂纹尖端塑性区对它的影响。

The bend strength and the refractoriness under load of the specimen in which mullte was used as a part of coarse particle were all higher than that the specimen with mullte the coarse particle.
粗颗粒中加入一部分莫来石与粗颗粒都为莫来石的试样相比具有更高的常温强度和高温荷重软化温度。

One of the specimen surface as the inner side, the other side as the outer surface, reciprocating bend it, until it is injured and record the bending number.
