...Yazhen Sun; Jiuhui Sun; Qingyuan Tan; Weiyi Tang; Yifeng Zheng; Jinchang Wang Purpose This study aims to investigate the deformation and cracking behavior during the opening construction process of cross-passages in super-large diameter shield tunnels. Design/methodology/approach This study...

... by replacing spatial derivatives in classical continuum mechanics with the integral term of long-range PD interactions, which enables such methods to be applicable to problems associated with complex crack propagation just by terminating the PD interactions between material points. However, the nonlocality...

...Wei Zhang; Beibing Dai; Zhen Liu; Cuiying Zhou Purpose The cracking of a reinforced concrete lining has a significant influence on the safety and leakage of pressure tunnels. This study aims to develop, validate and apply a numerical algorithm to simulate the lining cracking process during...

...K.A. Patel; Sandeep Chaudhary; A.K. Nagpal Purpose – The purpose of this paper is to develop, for use in everyday design, a procedure that incorporates the effect of concrete cracking in reinforced concrete (RC) beams at service load and requires computational efforts which is a fraction...

... cracking and microannuli openings at the interfaces of different materials such as casing/cement and cement/rock. In this paper, the possibility and order of magnitude of cement cracking and microannuli creation in the cross section of the well are assessed from a numerical case study within a classical...

... damage increments. The focus is on reinforced concrete structures, where multiple cracks initiate and compete to survive. Findings Compared to nonlinear smeared crack models in incremental‐iterative settings, the sequentially linear model is shown to be robust and effective in predicting...

... for the nonlinear behaviour of cracked concrete and the other associated features. Design/methodology/approach Geometric representation of the shell is enabled through multiple concrete layers. Composite characteristic of concrete is accounted by assigning different material properties to the layers. Steel...
