Atomistic models for friction suffer from the severe length- and time-scale restrictions of molecular dynamics. In this paper, a novel approach to quantify the scratching work and the energy associated with plastic activity is used. The approach is combine ...
Spring balances, based on Hooke’s law, have been used for weighing since the early 18th century. At the end of the century, naturalists such as Buffon felt the need to quantify the muscular force of men (humans) and animals. The first practical, portable “ ...
In the last decades the design of stepped spillways regained some interest because of their suitability with new construction methods including gabions. The hydraulic performances of gabion stepped weirs were investigated experimentally in terms of the flo ...
Even though friction affects everyday life in many ways, it is still one of the biggest mysteries of physics. Friction is a truly multi-scale phenomenon with a large variety of processes acting at various length and time scales. In recent years, much atten ...
We report on a new structure of Dielectric Elastomer Actuators (DEAs) called zipping DEAs, which have a set of unique characteristics that are a good match for the requirements of electrically-powered integrated microfluidic pumping and/or valving units as ...
We investigate the friction of deformable bodies, with nano-scale self-affine fractal rough surfaces, at the atomic scale using molecular dynamics. Different temperatures (0-400 K) are studied, while roughness and applied load are changed. During sliding, ...
Pressure tunnels are in operation subjected to internal water pressure. When the hoop tensile stress acting at the lining intrados exceeds the tensile strength of concrete, longitudinal cracks occur in the concrete lining. As a consequence of crack opening ...
A good biocompatibility, excellent mechanical properties and high corrosion resistance characterize CoCrMo alloys. Therefore they are widely used for artificial joints in biomedical implants. However, the degradation of the implants during service life lea ...
Atomistic models for friction suffer from the severe length- and time-scale restrictions of molecular dynamics. Even when they yield good qualitative results, it is difficult to draw meaningful quantitative conclusions from them. In this presentation, a no ...
We present a model that combines interface debonding and frictional contact. The onset of fracture is explicitly modeled using the well-known cohesive approach. Whereas the debonding process is controlled by a new extrinsic traction separation law, which a ...
