In this study, a generalized equivalent Stress Block Model has been proposed that is applicable to all types of concrete, including lightweight and high-strength concrete (HSC). First, available stress-strain models for concrete were verified through an extensive database. Then, the coefficients us...
The current Concrete Structural Design Code (2007) prescribe the equivalent rectangular stress block of the ACI 318 Building Code as concrete compressive stress distribution for design of concrete structures. The rectangular stress block may be enough for flexural strength calculation, but realistic stress...

Currently, the stress–strain curve of concrete developed in flexure is obtained by scaling down the uniaxial stress–strain curve. In current RC design codes, it is represented by an equivalent rectangular concrete stress block depending solely on the concrete strength. By comparing the theoretical ...

Let's consider the polar coordinate of which origin is the centre of the charge of explosives. Then, at any point in both the hard clay seam and the large block of concrete, the maximum values of the dynamic radial stress, γγ max, and the tangential stresses, θθmax and ΦΦmax, ...
