Viscoelastic characterisation of asphalt mixtures is an important component for modelling and performance prediction flexible pavements. In this study, using spherical indentation testing measuring the viscoelastic properties explored. Indentation may provide interesting alternative to existing experimental techniques, as it capable characterising small material volumes. Thus, become a useful t...

Indentation tests at scales on the order of one micron have shown that measured hardness increases signi_cantly with decreasing indent size\ a trend at odds with the size!independence implied by conventional plasticity theory[ In this paper\ strain gradient plasticity theory is used to model materials undergoing small!scale indentations[ Finite element implementation of the theory as it pertain...

Although many studies on the mechanical properties of brain tissue exist, some controversy concerning the possible differences in mechanical properties of white and gray matter tissues remains. Indentation experiments are conducted on white and gray matter tissues of various regions of the cerebrum and on tissue from the thalamus and the midbrain to study interregional differences. An advantage...

Abstract The rotating resistance of conveying belt accounts for the largest proportion running conveyor. To analyze key factors affecting its size, a simulation analysis relationship between conveyor load, idler diameter, speed, and indentation rolling was conducted based on finite element method. According to content, experimental verification carried out, test method formed. conclusions can p...
