A detailed study of the strain-hardening on a Fe-9Cr-0.1C tempered martensitic model alloy has been undertaken in the temperature range of 77-343 K. The true stress-true strain curves were calculated from tensile test data. In the framework of a phenomenol ...
Modeling of the constitutive behavior was undertaken for Fe- Cr-C tempered martensitic alloys. Tensile tests were carried out at room temperature and constant nominal strain rate. In order to obtain a fully martensitic structure with different prior austen ...
An assessment of the true stress-true strain relationship has been done by means of tensile and small ball punch tests on austenitic and tempered martensitic steel at room temperature. A finite element model was developed and validated to calculate the for ...
Plastic deformation under uniaxial longitudinal tension and compression is investigated for pure aluminum reinforced with a high volume fraction of parallel alumina fibers. The matrix sub-structure is also examined in transmission electron microscopy. The ...
The numerical simulation of concrete dams subject to earthquake loading requires realistic material laws which take into account material properties as effected by seismic action. Experiments under simulated seismic action were performed to examine the eff ...
The attachment of the first wall modules of the ITER FEAT fusion reactor is designed using flexible connectors made from titanium alloys. An assessment of the tensile and fatigue performance of two candidate alloys, a classical two phase Ti6Al4V alloy and ...
A new criterion for the appearance of hot tears in metallic alloys is proposed. Based upon a mass balance performed over the liquid and solid phases, it accounts for the tensile deformation of the solid skeleton perpendicular to the growing dendrites and f ...
The inventive device for measuring forces, in particular radial forces produced on an axis or another piece, for example on the axis of the rear wheel of a motorcycle. Said device comprises a measuring sleeve (1) arranged around an axis (3) in such a way t ...
The possibility of decreasing ultimate tensile strength associated with increasing fiber/matrix interfacial sliding is investigated in ceramic-matrix composites. An axisymmetric finite-element model is used to calculate axial fiber stresses versus radial p ...
