A comparative analysis of several nonlocal fracture criteria [PDF]
, 1998 Comparative analysis has been carried out for three nonlocal fracture criteria (NLFC) in application to plane problems: the average stress fracture criterion (ASFC), the minimum stress fracture criterion (MSFC) and the fictitious crack fracture criterion

Comparative study on mechanical properties of concrete for a hydraulic complex project
Shuili Shuiyun Gongcheng Xuebao, 2023 In order to discuss the mechanical properties and fracture characteristics of dam concrete, a three-point bending test of concrete beam was carried out based on two different concrete mix ratios (named C0.48 and C0.43 respectively according to different ...

Fracture analysis of debonding mechanism for FRP plates [PDF]
, 2009 Inevitable flaws in the concrete-FRP interface govern plate debonding, and are not amenable to finite element analysis because the models require far more detail than will ever be available for the interface. This thesis describes a global-energy-balance

SSRN Electronic Journal, 2022 In this study, the formulation of the two-parameter model based on the size effect proposed by previous researchers was initially improved to be much more practical. Subsequently, six series of notched and unnotched beams with a size ratio of 1:4 and notched and unnotched square prismatic specimens with a size ratio of 1:6 were tested to verify this ...

Multi-parameter fracture mechanics
Frattura ed Integrità Strutturale, 2019 A mixed-mode geometry has been chosen to investigate a crack propagation using the multi-parameter fracture mechanics concept. The so-called Williams’ series expansion is used for the crack-tip stress field approximation. It has been shown that application of the generalized fracture mechanics concept can be crucial for materials with specific fracture

Effect of internal crack defects on fracture properties of concrete
Shuili Shuiyun Gongcheng Xuebao, 2020 Concrete beams with different types of horizontal crack defect were designed and tested through the three-point bending test to investigate the influence of internal crack defect on the fracture behavior of concrete.
