建立SRM的思路可以扩展到3DEC中, 使用Voronoi块体表示混凝土,与DFN相结合能够模拟混凝土真实的破坏行为. 不过这种计算代价太大,需要性能非常高的计算机才能在短时间内得出结果。 [1] E.I. Al-Sahawneh Size effect and strength correction factors for normal weight concrete specimens under uniaxial compression stre...
It is the tensile strength only its compression strength of 8 % to 14 % . As a result, low-tensile capacity in its loading early will form a curved cracks. 翻译结果5复制译文编辑译文朗读译文返回顶部 When concrete bearing displays very strongly, but is pulled time displays very weakly.Its ...

7.2.1 Tensile strength Tensile strength is a measure of the force required to pull something such as rope, wire or a structural beam to the point where it breaks. There are three different versions of tensile strength: • Yield strength: the stress beyond which the strain in the material ...
When the concrete compression performance is very strong, but weak in tension when the performance of its tensile strength is only eight per cent of its compressive strength to 14%. Because such a low tensile strength, earlier in its load to form curved cracks. ...
However hardness, compression strength and heat deflection temperature (HDT) slightly decrease. Incorporation of DCPD molecules into unsaturated polyester chain causes an improvement in flexural strength, compression strength and hardness and also...

a混泥土受压时表现很强,但受拉时表现很弱。它的抗拉强度只有它抗压强度的百分之八到百分之十四。由于这样低的抗拉能力,在它的荷载早期就会形成弯曲的裂缝 When concrete bearing displays very strongly, but is pulled time displays very weakly.Its tensile strength only then its compressive strength 8% to 14...
The invention concerns a method of measuring tensile strength, compression strength and hard rocks impact strength, consisting in collecting from a orogen shapeless fragments of rock, preparation of samples from collected fragments of rock, subjecting the samples to measurement of speed of ultrasonic ...
When concrete is under pressure, but a very strong performance, subject to performance at a very weak. It is the tensile strength only its compression strength of 8 % to 14 % . Because of this low tensile capacity of loading, in his early will form a curved cracks. ...
