Moreover, there exist crack bridging, crack deflection, crack branching and GNPs pullout mechanisms.
Chloride ions can infiltrate the concrete and corrode the reinforcement if there exists any cracking on the bridge deck.
No clear relationship appears to exist between crack width and chloride content for the average crack widths below 0.05 mm in Fig. 19a.
There are a lot of ways to get data from an iPhone: data can be backed up on Apple's iCloud service and a variety of techniques exist to crack open phones running older versions of Apple's operating system.
Although approaches exist for crack detection in the food industry, there is still a need to transfer and adapt it to the desired application especially with respect to inline measurement in the baking field such as dough sheeting.
The modified shear creep model shows promising results for estimation of failure time, shear creep deformation and long-term stability of a rock slope for cases where planar-type failure occurs along a crack or joint surfaces in which no cohesion exists in the crack or joint surface contacts.
Numerical investigations of plasticity induced crack closure using the finite element method typically assume: (1) the opening behavior remains independent of the simulated rate of crack growth, and (2) a threshold element size exists below which crack opening loads become mesh independent.
However, in the real implementation, it is more important to detect whether a crack exists in order to make repairing in spite of a wrong crack classification.
Before the inflection point in the micro damage-loading cycles curve, the main damage is caused by new micro cracks increase inside the limestone; while after this point, the new micro crack emergence is being restrained, and the existed micro cracks connect into rupture bands.
The stress distribution around the crack is normalized using the singular stress near the vertex since the crack exists in the singular stress field.
