One type of engineering material that is often used in transportation construction, especially for aircraft, automotive, ships, and other industries is aluminum alloy. Aluminum alloys have excellent mechanical properties, including corrosion resistance, l... see more

This paper presents a theoretical approach to fracture propagation in viscoelastic media, which combines a micromechanical reasoning and macroscopic thermodynamics arguments. Unlike cracks, fractures can be viewed as interfaces that are able to ... see more

Polycrystalline diamond compact (PDC) bits are commonly used drill bits in the petroleum drilling industry. Cracks often occur on the surface of a bit, which may result in the unexpected suspension of the drilling operation, or even accidents. Therefore, ... see more

The stress analysis structures with complex geometry where it is continuously amended by the crack growth, as in aircraft fuselages, usually requires the employment of numerical methods, since the presence of cracks in the structure raises difficulti... see more

This paper concerns with the down-stream propagation of waves over initially still water. Such a study is relevant to generate waves of large amplitude in wave tankof a hydrodynamic laboratory. Input in the form of a time signal is provided at the wave-ma... see more

Equidiffusive combustion is a model, which is widely employed in analytical and computational studies, including those on premixed flame acceleration. However, realistic combustible mixtures are oftentimes far from the stoichiometry, being thereby strongl... see more

An in-depth analysis of the dynamics connected to the Doppler-effect brings clear light to elements of contradiction with the original ground on which the axiom of the constancy of lightspeed was based. Thereby, with regard to electromagnetic phenomenolog... see more

There would be no communication, business transactions or propagation of culture and beliefs but for the existence of language. Language is the most important tool for communication. The utterances human beings make are being governed by situation, event ... see more

Context. Solving the different applied problems of engineering and petroleum geology, geophysics and geodynamics, researchers often use methods based on phenomenon seismic-electrical effect of the second kind, since the electromagnetic field of electrical... see more
