The debonding behaviour of fibres strongly affects the properties of fibre-reinforced composites. In the literature, two different approaches to the fibre debonding problem have been developed. In strength-based approaches [1-4], interracial debonding is assumed to occur once an interfacial strength is reached. In fracture-based approaches [5-9], the debonded interfacial zone is regarded as a t...

The onshore oil and natural gas industries of China have started a large-scale development when crude oil reserves have been difficult to recover. The stratum fracture modification is an indispensable measure to efficiently develop oil and gas fields. Hydraulic fracturing is the most important reservoir stimulation technique, but it is still faced with various problems such as the failure to fr...

The way fractures affect seismic waves depends on fracture mechanical parameters, such as compliance and saturating fluid, and on their geometric properties, such as dimensions and spacing. When fractures are small relative to the seismic wavelength, waves will be weakly affected by fractures, and in effective medium theory, a zone comprised of many small fractures is equivalent to a homogeneou...

Reduced-order modeling is a promising approach, as many phenomena can be described by a few dominant modes/mechanisms. The goal of this paper is to assess the utility of Reduced-Order Models (ROMs) developed from three-dimensional physics-based models for predicting transient thermal power output for an enhanced geothermal reservoir while explicitly accounting for uncertainties in the subsurfac...

Thermal conductive heating (TCH) is an innovative remediation technology developed for aggressive in-situ non-aqueous phase liquid (NAPL) source zone treatment. Electrical heater wells are used to conductively transfer heat into the subsurface, thereby elevating temperatures and boiling both ground water and NAPLs. The design of a TCH remediation system needs to consider the cooling effect of i...

We propose a new method to investigate stress homogeneity along plate boundaries based on the cumulative misfit of individual fault plane solutions, calculated using assumed stress tensors. Using this method, some segments of faults can be defined, without the time-consuming inversions for stress directions from earthquake fault plane solutions. We assume that the misfits are relatively constan...
