Infants' tactual discriminative abilities and intermodal transfer were investigated in two research studies which endeavoured to answer two questions: can infants aged 4-5 months process and discriminate tactually information about different spatial arrangements of elements of an object, in the absence of visual control, and secondly, can they transfer this(More)
1. Abstract The present study proposes a comparison between several martensitic and ferritic steels in terms of creep strength and cyclic softening effect. The damage mechanisms are identified using fractographic observations and the microstructural evolutions are observed by TEM. The effects of a modified chemical composition on the high temperature(More)
A methodology for measuring the fracture toughness at crack initiation and the crack extension resistance of the molten zone of resistance spot welds under Mode I loading has been developed. The cross tensile test of U-shaped specimens was modified by crack growth monitoring and stress intensity factor determination. The resulting values of fracture(More)
The development of Generation IV fission nuclear reactors and fusion nuclear reactors requires materials able to resist to high temperature (650°C) creep, but also to creep-fatigue. Martensitic 9-12%Cr steels are candidate materials for these applications. Recent studies on commercial P91 steel showed that cyclic loadings coupled to high-temperature creep(More)
