The relationship between the deformation-strength properties of linear and three-dimensional polyhydroxyethers and the molecular weight of these polymersThe deformation properties of linear polyhydroxyethers with molecular weights ranging from 1000 to 70,000 were investigated and the data obtained were ...
Spearman Rank Order correlations were used to determine the relationships of eccentric strength and power with dynamic balance. Multiple linear regression, adjusting for age, mass, stature, playing experience and competitive level was performed on significant relationships. Normalised reach score in the ...
It is not appropriate to analyse a non-linear relationship using a Pearson product-moment correlation. Note: Pearson's correlation coefficient is a measure of the strength of a linear association between two variables. Put another way, it determines whether there is a linear component of ...
The 28-day compressive strength–UPV and strength–age statistical relationships at w/c ratio of 0.5 determined from the velocity–strength data set in linear, power, logarithm, exponential and polynomial trend forms. The polynomial trend line in the formy=aln(x) atR2value of 0.989, found ...
Stress distribution and stress transfer of carbon fiber reinforced composite material can be measured by using Raman spectrum, in terms of the linear relationship between the frequency shift of Raman spectrum and fiber strain. Cooperating with this technology, stress distribution of composite materials ...
It is often considered that linear relationship exists between the uniaxial compressive strength and Young's modulus of rock. There is some misunderstanding in this. Uniaxial compressive strength is sensitive to structure in property while Young's modulus is insensitive to structure in property. There...
Figure 3 Tensile stress–strain curve of concrete. Full size image Before concrete cracking, the stress σφ(ρ) and strain εφ(ρ) shows a linear elastic relationship, and the stress–strain slope is Ec. After concrete cracking, the concrete begins to soften, and εφ(ρ) ≥ εct...
The stress strain relationship of super high strength concrete appears to be linear, and sudden explosion occurs during compression failure. It illustrates ... 蒲心诚,王志军,王冲,... - 《建材发展导向》 被引量: 110发表: 2002年 Relationship between impact energy and compression toughness energy of...
The relationship between Brinell hardness and tensile strength for all the filler loading levels was studied using linear regression method. The strong correlation was found between the Brinell hardness and tensile hardness of the WPCs as the filler content was between 30 and 40wt%. The strong ...
