Sentence examples for shaft material from inspiring English sources
The shaft material is assumed to be elastic perfectly plastic.
Non-proportional viscous damping model is used to model the bearing and shaft material damping.
There are two reasons for the instability to occur in rotating slender shafts––rotation in the presence of internal friction in the shaft material, and the follower load.
The IESM is applied on state space representation of equations of motion and is used to identify bearing stiffness, damping and shaft material damping parameters.
The experimental identification of viscous coefficient of shaft material damping was not found in the available literature and this work attempts the same as well.
It is also shown how the destabilizing influence of the shaft material hysteresis can be counterbalanced by the other external dissipative forces.
Cell counting of five sections each showed that about 40% +/− 16.5% of all osteocytes in the cortical bone matrix of P17 tibiae were β-gal+, the majority of them being located at the endosteal side of the cortical bone shaft (supplementary material Fig. S3A).
With wood-shaft-era material, you want age, a known maker, rarity, distinctiveness and decent original condition (no massive head cracks, please).
We distinguished two methods of releasing a 'basic tool', by scoring the place where the subject gripped the plant material (root shaft, hook shaft, tool shaft, or joint; Fig. 1e) and the place of subsequent detachment (Fig. 1f): if these were identical, the behavioural action was considered a 'cut', and otherwise a 'pull' (Fig. 1g).
The Discrete Element Method (DEM) is used to model a drilled shaft in granular material.
Due to diversity of agricultural materials associated with different elastic plastic properties, a prerequisite for a reasonable measurement is to preclude the effect of penetration friction component (PFC) between the penetration shaft and surrounding material during a penetration process, otherwise an additional error may be significantly induced relating to the cone penetration depth.
