... of the mechanical behavior of concrete. Two characteristic parameters of FPZ were used to study the size effect of concrete. It is found that with the increase of size, the FPZ will develop deeper at peak load. However, the ratio of the maximum length of the FPZ to the initial ligament length does not vary...

... previously difficult to characterize. However, the specimen size effect is not consistent between different steels, as demonstrated for this new geometry herein. Tensile property measurements taken with noncontact extensometers from specimens of three different sizes from three different sheet steels showed...

Krupka The natural variation of strength properties within brittle materials leads to the phenomenon of size effect which causes the expected strength of a material to decrease as the stressed volume increases. An important implication of size effect...

Size effect was more pronounced in the early part of the load-deflection curve and decreased with an increase in the fiber volume fraction. At a given fiber volume fraction, the COV, moduli of rupture, and post-crack residual strengths...
