Is there any size effect and material variability aspects on the Compressive stress-strain response of burnt-clay brick and concrete brick units during the compressive strength test.
Dear Pankaj
In general, size effect is the dependency of the nominal strength of a material to the dimension of the test specimen. To be more clear, In design of steel/concrete structures one should assume one specific strength of steel/concrete. For instance, In concrete most of the international codes use the 150*300mm cylindrical specimens for compressive strength. However, if you test other size or shapes of specimens they would yield different results depending on their size. In massive structures, this phenomenon could lead to wrong design solutions. This phenomenon is called size effect. There are a lot of researches in this field which the earliest goes back to the research of Leicester and the most famous is the research of the Bazant and Planas. However, some notable scientists such as Prof. Xiao Zhi Hu, Prof. Carpinteri, and Prof. Sener played important roles in this field. You can also see my researches in this field for more information.

There is. If you read the articles in my profile you will see size effect and material variability aspect on stress-strain behavior. We studied types of ceramic bricks and of concrect bricks. The stress-strain gains due to size will be greater if the compressive resistance of the bricks are smaller.
