TAILIEUCHUNG - Fracture of high performance materials under multiaxial compression and thermal effect

The article discusses the strength of concrete and other brittle materials in the case of nonuniform biaxial type of compression (σ1 > σ2 > 0) and triaxial compression of σ1 > σ2 = σ3 > 0 type (it was assumed that σ> 0 corresponds to compression).

It is noted that when considering Available online 6 February 2017 the biaxial loading in the accepted model probabilistic nature of distribution of stresses along Keywords the contour of pores and inclusions . stress causing formation and propagation of cracks in Strength the material plays an important role. Moreover the stress across the circuit pores was regarded Multiaxial compression as a three-dimensional random field of S α β γ ω where ω - is a random argument. Considering Compressive and tensile stresses the average number of overshoots NR we believed that the random field of S is not homogeneous Temperature effect
