The size effect on J-R curve for construction steels and its prediction by simplified mechanical model
Evaluation of mechanical properties from a small amount of test material is essential in a process of development of new alloys and monitoring of degradation and damage of in-service components. Miniaturization of test specimen together with a specim...

Distinguishing between slip and twinning events during nanoindentation of magnesium alloy AZ31
Nanoindentation was performed in selected grain orientations close to [11-20] and [10-10] in magnesium alloy Mg–3Al–1Zn. The atomic force microscopy (AFM) and electron backscatter diffraction (EBSD) were used to examine the nanoindentation imprint. T...

Determination of mechanical properties of light alloys and composites by means of Small Punch Testing
Mechanical properties of magnesium alloys were evaluated from SPT and correlated with results of uniaxial tensile tests. SPT characteristics were converted to uniaxial tensile properties by empirical formulas available in the literature. New formulas...

Modelling of the stiffness evolution of truss core structures damaged by plastic buckling
A finite element study based on 1D beam element model is performed in order to investigate the mechanical behavior of an elasto-plastic beam loaded in axial compression over its buckling limit. The mode of loading is related to the damage of truss-co...

Stiffness and strength degradation of damaged truss core composites
Truss core laminates display stiffness and strength/density ratios superior to those seen in foam cored laminates. However, this superiority is held only for ideal shaped struts. If the truss core is damaged, its performance rapidly decreases towards...

The prediction of size effect on J R curve for Eurofer97 steel by simplified mechanical model
The possibilities to derive fracture toughness from small specimens are naturally limited due to constraint requirements which are especially restrictive in toughness testing. The loss of constraint at the crack tip is more likely to occur as specime...
