Crack spacing threshold of double cracks propagation for large-module rack

Journal of Central South University, 2015
Large-module rack of the Three Gorges shiplift is manufactured by casting and machining, which is unable to avoid slag inclusions and surface cracks. To ensure its safety in the future service, studying on crack propagation rule and the residual life estimation method of large-module rack is of great significance.

Crack spacing and crack width investigation from experimental CRCP sections

International Journal of Pavement Engineering, 2006
Crack width (CW) and crack spacing (CS) data from full-scale continuously reinforced concrete pavement (CRCP) test sections were collected and analyzed for this study. In order to compare CWs obtained under different temperature conditions, the CRCP CW model presented in the new mechanistic–empirical pavement design guide (MEPDG) was utilized to ...

Crack space and crack width of weldmesh ferrocement under cyclic loading

Cement and Concrete Composites, 1994
Abstract As part of a large programme, a study of crack width under cyclic loading has been carried out. The crack space, which is thought to be one of the most important factors influencing crack width, has received special attention. Test results and theoretical studies show that the cracks in the ferrocement tested have an insignificant influence ...

Evaluation of tension-stiffening, crack spacing and crack width of geopolymer concretes

Construction and Building Materials, 2018
Abstract This paper presents the results of an experimental study on the behavior of twenty geopolymer concrete prisms tested under uniaxial tension to investigate the tension-stiffening effect on the deformation and crack width of geopolymer concretes, prepared using either fly ash-based geopolymer concrete or granulated lead smelter slag (GLSS ...

An elastic quarter space with an extending crack

Engineering Fracture Mechanics, 1996
The dynamic anti-plane problem of a crack extending from the corner of an elastic quarter space with a constant subsonic velocity due to sudden application of mechanical disturbances in the outer surfaces of the quarter space has been considered. The problem has been solved using the self-similarity technique, which is based on the observation that for

The Cracks in Detroit: Stories of Hopeful Bodies in Desolate Spaces

2016
AbstractDetroit scares the hell out of most people. If it doesn’t scare you it will shock you. Sprawling over more area than Boston, Manhattan and San Francisco combined, Detroit’s population has declined 63% since 1950. There are currently 78,000 abandoned structures, and an unemployment rate of over 18%.

Regularity of the transverse crack spacing in a damaged laminate

Reliability Engineering & System Safety, 1997
Abstract In evaluating elastic constants for a damaged laminate, the assumption is often made that transverse matrix cracks are equally spaced. To investigate the plausibility of this assumption, an analytical expression for the probability density function of the next failure location in a region of the cross-ply laminate bounded by two existing ...

Using Surface Crack Spacing to Predict Crack Network Geometry in Swelling Soils

Soil Science Society of America Journal, 2000
Prediction of the geometrical characteristics of steady crack networks in swelling soils is possible using a previously published model based on concepts of multiple cracking and fragmentation. Applications of the model require estimation of the model parameters: the thickness of the upper intensive‐cracking layer,
