Master moulds are used to cast copper anode moulds. These iron moulds are made of grey or nodular cast irons. According to desirable properties of ductile irons, it was expected that ductile cast iron ...

Mechanisms for interpreting anomalous decreases in radon in ground water prior to earthquakes are examined with the help of a case study to show that radon potentially is a sensitive tracer of strain changes in the crust preceding an earthquake. The 2003 Chengkung earthquake of magnitude (M) 6.8 on December 10, 2003, was the strongest earthquake near the Chengkung area in eastern Taiwan since 1...

A meshfree method and (the related) a specified crack growth algorithm are used to simulate plugging fracture during high-speed impacts. In particular, we are simulating ballistic penetration of a steel plate, which is a ductile failure process involving projectile and target collision, contact, and subsequent projectile penetration companied plugging fracture inside steel plate. We have develo...

With interfacially engineered pseudo-ductile carbon fibre reinforced polymer composites, a higher energy absorption capacity and metal-like stress-strain response can be achieved during failure. Due to incorporated inter-layer additives deposited with fused filament fabrication, locally weakened zones printed on the surface of reinforcing material, which provides better capability composite lam...

Introduction: Mars exhibits a wide variety of landforms that are indicative of ductile flow, ranging from the viscous creep of ice-rich permafrost [1] to the glaciation of thick Martian ice sheets [2] to the surface mobility of thin debris flows [3]. All of these flow features probably contain significant amounts of dust, which for example will likely be present throughout the impact-disrupted ...

Metallic glasses, like many other glasses and ceramics, generally have zero tensile ductility. Distinct from common wisdom which seeks to toughen brittle with ductile phases, we show that composites made two can be ductile, strong even harden under tension as a result of microstructure stiffness contrast. Using molecular dynamics simulations, designed tested consisting alternating wavy nanofila...
