Abstract:
... Stretching of the Earth's upper crust is commonly accommodated by normal faulting, fault-related folding and/or fracturing such as veins and joints. However, an increasing number of outcrop-scale studies highlight that extension is also accompanied by bed-parallel slip (BPS). The identification of BPS surfaces is, however, challenging due to their localised nature within bedded host rock sequences ...

... In this work, a new structure for designing auxetic yarn and its geometrical analysis is presented. The proposed structure is referred to as a double-core helical auxetic yarn (DC-HAY). It consists of two core components of soft yarn with a larger diameter and one wrap component of stiff yarn with a smaller diameter. A primary geometrical model for predicting the Poisson’s ratio of the structure w ...

Abstract:
... Compared with monolithic materials, topologically interlocked materials (TIMs) exhibit higher toughness based on their enhanced crack deflection and deformation tolerance. Importantly, by reducing the block size of TIMs, their structural strength can also be improved due to the reduced flexural span. However, the assembly of microscale blocks remains a huge challenge due to the inadequacy of nanos ...

Abstract:
... Landslides are one of the most common geological disasters with the complicated spatiotemporal processes, which can be partially reproduced in slip shear failure along the discontinuity in laboratory tests. However, the assessment and evaluation of shear behavior along the discontinuity is time-consuming and high-cost. To solve this problem, a new constitutive model is proposed to predict the shea ...
