-linear distribution is suggested for approximate calculation of the bending stresses at mid-pier sections. The relationship is accordingly established among bending moment, edge stress of the section... of the mid-pier sections is simple and practical, and that the calculated precision is high. Key words: castellated beam; tubular voided slab; bending stress; flexural stiffness

is mixed with concrete. In this paper, based on micromechanics, fourpoint bending numerical models with and without glass fiber of different interfacial strength have been set up to simulate the damage...Effect of Interfacial Strength on the Flexural Behavior of Glass Fiber Reinforced Polymer(GFRP) Reinforced Concrete Beam张亚芳,YANG Wenlong,LIU Hao,CHEN Peiran,LIU FengFaculty of Civil Engineering......
Study on the Interface Bonding and Bending Fatigue Properties of Aluminum Alloy Foam Sandwich () 摘要:Foam materials have many attractive properties because of their low-weight and cell structure... sheet/powders precursor. Bending fatigue test results showed that the bonding force of the foamed sandwich interface is very high, in fatigue test fracture occurred in the whole foam aluminum sandwich......
that TaC with form of coating enwrap evenly and compactly around with the carbon fiber in C/C-TaC composites and form the cannular microstructure, both the average strength and toughness of C/C-TaC composites sample increase apparently. The average flexural strength of C/C-TaC composites sample reaches up to 270 MPa, approximately increases by 70% comparing with C/C composites. The maximum fracture......
region (point A) is Ti3Al phase, the darker lath is TiAl phase (point B), and there exists a little γ-region (point C). Static bending tests were carried out, and the flexural strength is 850 MPa...; Abstract: A new ultrasonic three-point bending fatigue test device was introduced to investigate fatigue life......

China 28(2018) 309-318 Effect of geometrical parameters on forming quality of high-strength TA18 titanium alloy tube in numerical control bending Jun FANG1,2, Chuang...; geometrical parameters; forming quality; finite element simulation; numerical control bending 1 Introduction High-strength TA18 titanium alloy tube (HS-TA18 tube) has attracted increasing......
">In this study, we examined the evolution of the texture and mechanical properties of 2060(T8) alloy during bending. A pixel rotation method(PRM) was proposed and used to characterize the textural evolution during bending determined by electron backscatter diffraction. The results showed that the textural components changed insignificantly, with the exception of a decrease in the cube texture......
