It is safe to say that such materials include wood and products made from wood-based materials.
As for large-scale cladding made from wood and wood-based materials, this rule applies doubly.
For the purposes of this research, the choice of materials was considerably simplified as the research focuses on wood or wood-based materials only.

Therefore, a lot of attention has been devoted to the understanding of these phenomena for their future application as sensor materials.
Hence, an investigation of the strength and deformation behavior of defect-free materials at nanometer level greatly facilitates the analysis of nano-components [4].
Young's modulus, E, can be calculated by dividing the tensile stress by the tensile strain on the loading plane along the loading direction in elastic deformation range of materials.

Experimental section Materials and chemicals S.aizoon was purchased from Hebei and dried in sunshine.
The powder was successively extracted with petroleum ether and ethanol (80%, V/V) using reflux condenser to degrease and remove some colored materials, oligosaccharides and some small moleculematerials[3].
The pre-treated materials were dried at 65℃ and stored in glass dryer prior to the experiments.
Extraction of crudes polysaccharides Polysaccharides extraction by hot water The pretreated materials were extracted at 97℃ for 126 min with ratio of the materials to water 15:1 mL/g.

Base on the previous researches, the paper classifies the slopes according to the types of rock-soil materials and the slopes structure, which have close relationships with the deformation features and failure modes of slopes.
In these methods, the classification by the types of materials and the slopes structure are closest to the deformation features and failure modes of slopes.
The slopes can be classified as soil slope, rock slope and rock and soil composite slope according to the types of materials.
So in the paper, slopes are classified according to the types of rock-soil materials, the slope structures and the main failure modes.
For the Mohr-Coulomb materials, the safety factor of strength reduction can be expressed as:.
