The essence of smeared crack model is smearing the actual materials’ cracks into the whole unit, using the material constitutive model to simulate the influence of cracks.
(1) Materials’ crack criterion Crack criterion is a strength criterion to judge whether the unit will crack.
So we first analyze small-cracks’ (inside the samples) influence on tensile strength, and evaluate open-model’s applicability to soil materials tensile crack at the same time.

Influence of Severe Plastic Deformation on Microstructure and Thermal Properties of Cu Kinga Rodak1, Grzegorz Moskal1 Silesian University of Technology, 1Department of Materials Science 40-019 Katowice, Krasińskiego 8str, Poland kinga.rodak@polsl.pl, grzegorz.moskal@polsl.pl Keywords: severe plastic deformation, ultrafine grained structure, EBSD, TEM, physical properties Abstract.
Ultrafine- grained materials generally offer high strength coupled with reasonably good fracture toughness and often superplastic properties at moderate temperatures and at high strain rates [1-3].
Materials and experiment procedure Investigations have been performed by use multi-axial compression techniques for refining Cu structure.

Secondly, automation communication must be based on communication materials.
And the communication materials are very full.
The correct choice of the materials will directly influence practice effeciency.
How do learners choose the best communication materials?

On the other hand, idealized brittle fracture defined in the framework of linear-elastic fracture mechanics does not strictly represent a precise, physical fracture mode in engineering materials, since most materials sustain a certain amount of plastic deformation before fracture takes place.
In addition, linear-elastic materials recover to their original, un-deformed, and hence un-damaged configurations upon unloading.

Very short ultrasonic pulse-waves with main frequencies ranging from 0.1-50 MHz are launched into materials in order to detect internal flaws.
The pulse is caused by the material thermoelastic expansion due to the material absorption of laser energy.
