Maximum shear strength

Determination of Fibre-Matrix Adhesion. The average shear strength x and maximum shear strength Xmax at the fibre-matrix interface CZ, 22) are given by... 

The values of the average and the maximum shear strengths T and w of the interface, as calculated from Equations 17 and 18, are presented in Table VI. 

Metals — steel, aluminium, titanium as hexagonal honeycomb (maximum shear strength, expensive). 

Constant U in Equation 3.12 is the bulk solid vibration velocity constant. Experience has shown that U is independent of the consolidation pressure and applied normal pressure. Knowing the value of U for a particular bulk solid, the values of the relative amplitude X, and the frequency/for maximum shear strength may be calculated from... 

With the pultrusion line and materials used here, the following process parameters lead to at least 80% of the maximum shear strength (Xmax 14 MPa as measured by the Lauke test [8]) at pulling speeds of at least 0.3 m/min ... 

Ultimate Drift in RC Members Other characteristic point of RC member force-displacement response is the ultimate drift capacity for each failure mode considered. Ultimate drift capacity is generally evaluated at the drift characterizing a 20 % loss of the maximum shear strength (FIB 2003) attained in the element see Fig. 4. According to the failure mode, different empirical ultimate drift capacity formulations are available in the literature. Most experimental databases are characterized by cyclic tests and few monotonic tests. Thus, most of those empirical formulations account implicitly for cyclic degradation. 

Sfu is the slip at maximum shear strength (Xfud) and Qc is the design compressive strength at the interface. 

In the model proposed by the Code of Structural Interventions (2012), the maximum shear strength value is calculated using the same equation proposed by CEB-FIP (1993). The variation of the shear stress with the slip is considered linear for slip equal or lower than 0.005 dB. For any value between 0.005 and 0.05 dB, the shear stress value is calculated using Eq. 8. This model is presented in Fig. 14. 

Fig.4 shows the maximum shear strength versus the mucus film thickness. The average mucus film thickness was decided as foUows. The mucus of 10 pi was set on a base glass of 5cm sq., and pressed and spread by another glass plate. The average film thickness was decided from the spread area and the volume of 10 pi. The pulling velocity was 1.26 mm/s,... 

The mechanical properties under tension are not sufficient to determine total material behavior. The properties under compression, flexure, and shear can be different. For ductile materials, it is generally assumed that the behavior in compression is the same as that in tension, that is, that the compressive strength is the same and that the modulus E is the same as obtained in a simple tension test. Also, for ductile behavior, the maximum shear yield strength under tension is taken as a measure of the maximum shear strength, such that... 

A wide range of analytical techniques were used to analyze the effects of the fiber surface modification on the performance of the composites. Average maximum interfaeial shear strength values greater than the maximum shear strength of the matrix were found to exist for some surface modified fiber composites. This was due to the presence of an interphase called the transcrystalline region which had greater mechanical properties than that of the matrix bulk material.
