Project

Resistance to brittle damage use of petrographic/ rock mechanical data for the technological-mechanical behaviour and serviceability of crushed stone (GA18-08826S)

derived stress-strain behaviour will be used for development of advanced analysis. This involves crack initiation and crack damage stress-strain thresholds that can be derived from stress-str...

Global analysis methods for slender structures of stainless steels and other steels with non-linear stress-strain diagram (GA20-24563S)

Modern steel material (e.g. stainless steel, HSS) exhibit significant degree of stress-strain nonlinearity affecting member behaviour significantly. The presented of structural behaviour for members of such materia...

Microstructural study of orthogneisses role of strain rate, stress and temperature (GA205/00/D043)

The orthogneisses are due to their simple mineralogical composition the appropriate rocks for microstructural study of deformational mechanisms of rock forming minerals and for rheological behaviour of the continental crust. Quartz, plagiocl...

Experimental study of crack initiation and crack damage stress thresholds as critical parameters influencing the durability of natural porous stone (GA13-13967S)

The durability of natural stone is assumed to be intimately related to pre-peak fracture process (crack initiation and damage), which can be derived from stress-strain behaviour during compression and/or tension. Compared t...
