With the rapid development of marine engineering construction, coral aggregate has been widely applied in practical engineering. Its creep characteristics must be emphasized, but only a few experimental studies have been conducted, and theoretical research has not yet been reported. In this study, based on the traditional Burgers rheological model ...

The requirement for lightweight materials that can survive increasingly severe conditions for aerospace components has fueled the research on magnesium alloys. The current work investigates the influence of hot rolling on the creep characteristics of the Mg-5Ag alloy that is fabricated through a selective laser melting process. The creep properties...
Pri razvoju mehansko in temperaturno obremenjenih strojnih elementov je ključno napovedati, kako se bo material odzval na tovrstne obremenitve. V prvem delu zaključne naloge je pregled literature na področju lezenja in relaksacije ter modeliranja napetostno-deformacijskih stanj. Namen diplomske naloge je na podlagi enačb iz literature napisati prog...

In the present study, Al/BN/Cu bimetal composite strips were fabricated via the accumulative roll bonding (ARB) process. Then, fracture toughness, mechanical properties, bonding strength, forming limit diagram (FLD), and creep properties have been studied via experimental techniques. The study of creep behavior and mechanical properties showed a fo...
An understanding of the rheological behavior of the solid Earth is fundamental to provide a quantitative description of most geological and geophysical phenomena. The continuum mechanics approach to describing large-scale phenomena needs to be informed by a description of the mechanisms operating at the atomic scale. These involve crystal defects, ...
A supposedly active rock instability was instrumented at Socoa (municipality of Ciboure, France). The objective was on the one hand to diagnose the activity of the instability, and on the other hand, to understand the meteorological-marine phenomena and associated processes which could play a role in its destabilization. Analysis of in situ data (e...
Oxide/oxide composites are ceramic matrix composites (CMC) designed for thermomechanical applications. When used at high temperatures, the progressive appearance of creep has been observed. Damage models are therefore no longer sufficient for dimensioning parts. In this paper, the creep of the material is studied experimentally in order to propose ...

The subsoil of Mexico City (SMC) is highly compressible when loads are applied. This feature is associated with many uncertainties and complex issues during foundation design processes. The compressibility of the SMC has been investigated since the 40s by using oedometer tests in most cases. However, the importance of the results in interpreting co...

Granular materials exhibit time- and rate-dependent behaviour resulting from micromechanical processes at the scale of individual particles. Elastic energy is released during these processes and can be detected as acoustic emissions (AE). Using multistage creep tests under isotropic and anisotropic pressure on medium dense samples of dry silica san...
Tato práce je zaměřena na problematiku zkoušení požární odolnosti konstrukce v peci a možnosti simulace chování konstrukce při požáru pomocí numerické metody. V další části je práce zaměřena na úvod do problematiky deformací oceli od tečení. Hlavním bodem je požární zkouška ocelového nosníku v peci, numerický model nosníku vytvořený v softwaru ANSY...
