produce a composite, which is typically accomplished by incorporating continuous fibers, whiskers, platelets, or second The high-temperature mechanical properties of an in situ phase particles (3). For monolithic ceramics, in situ toughening toughened silicon carbide, with Al, B and C sintering additives can also be effective with microstructures consisting of elongated (ABC-Sic), have been exa...

Understanding mechanical interactions at the root-soil interface is essential to predict erosion of vegetated slopes. Recently, shear strength vegetatedil under changing hydraulic conditions has been measured and modeled; however, interfaces have not investigated conditions. This paper proposes (1) a novel pullout apparatus measure suction, (2) Mohr-Coulomb-Vilar (MCV) model interfaces, (3) num...

To obtain a tensile strain-hardening behavior by using the ordinary polypropylene (PP) fiber, micromechanical model recommends increase of fiber low interfacial bond with an cementitious matrix. It was predicted that alkali-activated slag (AAS) composite high drying shrinkage performance would affect interface frictional during pullout.

This study investigates the effect of carbide particle size on the microstructure, mechanical properties, and abrasive wear resistance of WC-17%Co HVOF-sprayed coatings. The characteristics of WC-1, WC-2, and WC-3 coatings with carbide sizes of 1 µm, 0.9 µm, and 0.5 µm, respectively, were also investigated. WC-1 coating experienced the maximum carbon loss of 42%, while WC-2 and WC-3 coatings un...

INTRODUCTION Interference screws used in fixation of anterior cruciate ligament (ACL) hamstring grafts create mechanical hold by forcing the graft into frictional contact with the bone tunnel. We analyzed the resultant graft-tunnel contact pressure using an in vitro model of human cadaver 8mm hamstring grafts. METHODS Contact characteristics were assessed using both pressure sensitive films a...

OBJECTIVE The partially threaded cancellous lag screw (PTLS) could not provide maximum compressive force (C(MAX)) for compression due to compromised pullout strength (POS). The combined partially threaded cancellous lag screw (CPTLS) could provide higher C(MAX) than PTLS. However, the change of POS at the point of C(MAX) when using CPTLS for compression has never been explored. The aim of this ...
