The needle with triangle cross-section tip and larger size showed higher puncture force than that with round cross-section and smaller one.
This paper presents a method for solving problems of transient response in flexure due to general unidirectional dynamic loads of beams of variable cross section with tip inertias.
This paper is concerned with a method for solving seismic response problems of a pile of variable cross section with a tip inertia subjected to a sea bottom seismic displacement.
The pores have a triangular cross section and pore tips and grow along the two available "downward" <111> B directions of the crystal ("channels" or lines in the plane of view in Fig. 1a) and into the two available "upward" <111> B directions, intersecting the plane of view in Fig. 1a, giving the appearance of triangular holes.
Fluorescence observed in root tip cells as a result of morin staining depicts Al-accumulation while both light microscopy of Al-treated root tip cross sections and root tips stained with Evan's blue, which is a dye that measures extent of cell death, indicates cell death.
The bSi-1 surface was found to possess well-separated pillars, which were approximately 625 nm long and 81 nm in diameter at their widest cross section close to the tip.
In addition to general combination of geometrical dimensions and material properties, the formulas are also explicitly expressed in terms of generic stress resultants in the cross section at the crack tip.
Figure 6a to d show the SEM images of the cross section of the fiber tip showing the thickness of the rGO layers with concentrations of 0.2, 0.5, 0.75, 1.0 mg/mol The average thickness of the rGO layer with concentrations 0.2, 0.5, 0.75, 1.0 mg/mol is 292 nm, 290 nm, 279 nm and 362 nm respectively.
Fig. 4 The left column (a d) shows the experimental and simulation results of the probe with Rr = 1.50 μm, while the right column (e h) illustrates that of Rr = 1.90 μm, (a) and (e) Measured and (b) and (f) calculated optical field distribution and (c) and (g) calculated phase distribution and (d) and (h) calculated cross section of the probe tip.
We modeled rodent whiskers as truncated cones with a cylindrical cross section, base radius rbase, tip radius rtip, and length LW (Ibrahim and Wright, 1975; Boubenec et al., 2012).
The hollow quills of New World porcupines are sharp, stiff, and circular in cross section and have barbed tips.
