Crack opening model
WebMay 7, 2024 · The parameters of the model include the tensile strength of concrete f t, the turning point stress σ 1, the crack opening displacement w 1, and the critical crack opening displacement w 0. In the study, the tensile strength obtained from the research by Chen et al. ( 2024 ) can be used and the value is 4.16 MPa. WebTo investigate the influence of joints on the stability of underground opening, uniaxial compression tests and FE analyses based on a microplane damage model for rocks has been conducted for rock-like models with a circular hole and a set of non-persistent joints. It was found that the peak strength and Young’s modulus decrease with the increase in …

WebThe aim of the present work is to extend the two-phase local/nonlocal stress-driven integral model (SDM) to the case of nanobeams with internal discontinuities: as a matter of fact, the original formulation avoids the presence of any discontinuities. Consequently, here, for the first time, the problem of an internal discontinuity is addressed by using a convex … WebThe analysis has been made using the crack opening displacement from long cracks combined with the appropriate weight function to compute the crack closure stresses by crack bridging as a function of crack opening displacement. ... This study is aimed at proposing a simple analytical model to investigate the post-cracking behaviour of FRC ...
WebAn important feature of the cracking model is that, whereas crack initiation is based on Mode I fracture only, postcracked behavior includes Mode II as well as Mode I.
