In this study, a series of laboratory experiments including triaxial compression tests, acoustic emission (AE) monitoring and discrete element numerical simulations, combined with a self-developed high-performance copper...

The self-sealing and self-healing behaviors of technological gaps in a high-level radioactive waste repository are analyzed. The systematical findings are summarized based on the previous studies on the effects of techno...

Volume changes take place during the fully undrained compression tests on unsaturated soils. It is more difficult to simulate the undrained mechanical behaviors of unsaturated soils than those of saturated soils. In this...

Abstract Over the last two decades, researchers have focused on natural reinforcement composites as choice to conventional and man-made fiber composites due to their enhanced properties. While many research has studied t...

Soft clay is influenced by the time-dependence of viscosity and consolidation as well as coupling effect of moisture. In order to study the effect of moisture content on soft clay foundation, by introducing the elastic-v...

With the help of ABAQUS FEM software, a numerical study is carried out on the mechanical properties of bent bolted connection in shield tunnel under the effect of preload, which offers theoretical evidence for the design...

This study investigates how four nano-additives, namely graphene, amine-functionalized graphene, hexagonal boron nitride (hBN), and multi-walled carbon nanotubes, affect the properties of polylactic acid (PLA) used in ma...

Abstract Grease is extensively used in rolling bearings due to its inherent sealing properties. However, mechanical degradation typically occurs, resulting in a significantly shorter lifespan for the grease compared to t...

In the present work, the mechanical performance of polylactic acid (PLA) based composites reinforced with hydroxyapatite (HA) or β-tricalcium phosphate (β-TCP) was investigated. The polymer was melt compounded with 1 a...

Abstract Shell-infill structures comprise an exterior solid shell and an interior lattice infill, whose closed features yield superior comprehensive mechanical performance and light weight. Additive manufacturing (AM) ca...

To investigate the dynamic mechanical behavior and fragmentation characteristics of layered rock under the combined effects of chemical corrosion and impact loading, split Hopkinson pressure bar (SHPB) tests were perform...

ABSTRACT Degradation of bovine small intestine and respective effects on biomechanics have not been described to date. Biomechanical testing of intestinal tissues is often carried out within a few hours of donor death an...

Abstract Jurassic sandy mudstone formations are common in the Ordos mining area, and the diagenetic period is relatively late. The lithological characteristics and creep mechanical properties of this formation form the b...

This work investigates the mechanical behavior of recycled steel fibers recovered from waste tires and, then, suitable to produce eco-friendly fiber-reinforced concrete. Particularly, the results of an experimental inves...

Abstract With the combination of 3D printing and electroplating technique, metal-coated resin lattice is a viable way to achieve lightweight design with desirable responses. However, due to high structural complexity, me...

Abstract The axial collapse mechanical behavior and energy absorption characteristics of circular foam-filled tubes mimicking the bamboo characteristics under quasi-static and low-velocity impact loads were investigated ...

Abstract The crystal plasticity finite element method (CPFEM) is widely used to explore the microscopic mechanical behavior of materials and understand the deformation mechanism at the grain-level. However, few CPFEM sim...

Vegetable derivatives like peanut protein concentrates constitute an alternative for incorporation in starch-based systems. In order to assess the capacity of peanut protein concentrate (PPC) to be incorporated in starch...

Flat subduction segments are generally related to cold lithospheric zones, which suggest low Heat flow values and therefore a deeper Curie isotherm. In this study we perform a geophysical analysis by using high - resolut...

As a novel reactive damage material, high-entropy alloys (HEAs) have garnered widespread attention in the field of reactive damage in recent years due to their excellent mechanical properties and favorable energy release...

Abstract Cast iron alloys with low production cost and quite good mechanical properties are widely used in the automotive industry. To study the mechanical behavior of a typical ductile cast iron (GJS-450) with nodular g...

Abstract With the rapid developments of marine resource exploitation, mounts of marine engineering equipment are settled on the ocean. When it is not possible to move the damaged equipment into a dry dock, welding operat...

In this work, lignocellulosic fibers from rapeseed harvest residues were used to develop bio-based insulating foams as an alternative to petroleum-based materials, investigating the influence of the fiber extraction meth...

Abstract Backgrounds Nickel-titanium (NiTi) rotary instruments are widely used in endodontics because of their flexibility and superelasticity. However, the cyclic fatigue resistance of ORODEKA and M3-L systems in curved...
