the main objective of this study is to drive a simple solution for prediction of steel fiber reinforced concrete (sfrc) behavior under four point bending test (fpbt). in this model all the force components at the beam section (before and after cracking) are formulated by applying these assumptions: a bilinear elastic-perfectly plastic stress-strain response for concrete behavior in compression,...

An analytic expression describing the complex voltage measured between the pickup points of a four-point probe, in contact with the surface of a half-space conductor, is derived. The driving current is assumed to be time harmonic. There are two contributions to the measured voltage. One arises from the potential drop due to electric current flowing in the conductor. The other arises from induct...

Laser surface remelting can be used to manipulate the microstructure of cast material. Here, we present a detailed analysis Fe$_2$VAl following laser remelting. Within melt pool, elongated grains grow nearly epitaxially from heat-affected zone. These are separated by low-angle grain boundaries with 1{\deg}-5{\deg} misorientations. Segregation vanadium, carbon, and nitrogen at dislocations is ob...

where F : J ×Rn → (Rn) is a multivalued map, (Rn) is the family of all subsets of Rn, y0 ∈ Rn, and 0 ≤ t1 < t2 < ··· < tp ≤ b, p ∈ N, ck = 0, k = 1,2, . . . , p. The single-valued case of problem (1.1) was studied by Byszewski [5], in which a new definition of mild solution was introduced. In the same paper, it was remarked that the constants ck, k = 1, . . . , p, from condition (1.1b) can sati...

Traditional scanning transmission electron microscopy (STEM) detectors are monolithic and integrate a subset of the transmitted electron beam signal scattered from each electron probe position, shown schematically in Figure 1. These convergent beam electron diffraction patterns (CBED) are extremely rich in information, containing localized information on sample structure [1], composition [2], p...

Spin–orbit torque (SOT) characterization techniques generally require the Hall cross that demands lithography resources and time. It is highly desirable to characterize SOT efficiencies with minimal sample processing Here, we demonstrate a lithography-free technique determine spin–orbit efficiency in perpendicular magnetic anisotropy ferromagnetic heterostructure. By utilizing customized four-p...

The term integrable asymptotically conformal at a point for a quasiconformal map defined on a domain is defined. Furthermore, we prove that there is a normal form for this kind attracting or repelling or superattracting fixed point with the control condition under a quasiconformal change of coordinate which is also asymptotically conformal at this fixed point. The change of coordinate is essent...

The electrical performance of graphene synthesized by chemical vapor deposition and transferred to insulating surfaces may be compromised by extended defects, including for instance grain boundaries, cracks, wrinkles, and tears. In this study, we experimentally investigate and compare the nano- and microscale electrical continuity of single layer graphene grown on centimeter-sized single crysta...
