In most specimens, the tensile strength of mortar was experimentally obtained, whereas in some data available in the literature the tensile strength of mortar was not given and it was calculated according to the formula of EC2:(19)ftm = 0.3fcm2/3where fcm is the compressive strength of ...
fwy the yield strength of steel shear reinforcement, ft tensile strength of concrete, Vcrack the shear force at diagonal shear cracking suggested in JSCE-2007 standard specification, V the applied shear force, Vs+f′ the shear force carried by steel shear and fiber reinforcements, θ the strut...

During strain hardening of a steel alloy, determine the trend in the following properties. (choose either increase, decrease, or no change) Strength ___ Ductility ___ Elastic modulus ___ Describe how the values of resistivity determine the uses of material in the industry? Expla...
·OH signal strength of BFO/BiOI are negligible in the dark. However, when both conditions of light and external force are performed, BFO/BiOI show a very strong ·OH signal and ·O2-signal (Fig.4e). Experimental evidence has demonstrated the participation of ·OH and ·O2-radicals in the...
The required pretreatment of CAD/CAM ceramic materials before resin composite cement application varies among studies. The aim of the present study was to evaluate the effect of hydrofluoric acid concentration and etching time on the shear bond strength
If this material had a tensile yield strength of 100 ksi, the max. shear stress theory would predict yielding, but the VonMises would not. Where is my error? By the way, I know where the error is, but am looking all over the place for a good description of why, and how to ...
If the shear strength of the matrix is larger than that of the interface, Eq. (9-9) gives the interfacial shear strength, otherwise it is matrix strength. The shear modulus, G13c, of unidirectional fiber composites can be determined by the role of mixtures. However, the following formula ...
There are two disadvantages of using parallel bonds in simulating the brittle failure in the intact rock: (1) a significantly higher ratio of uniaxial compressive strength to tensile strength (σc/σt); and (2) a low macroscale intact rock friction angle (maximum is around 30°). When ...
where ∆τmax = maximum shear stress range, tA,B = shear fatigue strength, σuts = ultimate tensile strength. Van [37] proposed an endurance limit criterion, also known as the Dang Van model, based on the concept of micro-stresses within a critical volume of material, expressed in Eq....
