Fracture properties of notched and pre-cracked specimens of a tempered martensitic steel at low temperature

Philippe Spätig, Raul Alejandro Bonadé, Pablo Federico Mueller

The fracture properties of the 9CrWVTa reduced-activation tempered martensitic steel Eurofer97 were studied in the lower ductile to brittle transition. Sub-sized pre-cracked compact tension and notched tensile specimens were tested. Finite element simu ...

Extension of the Uniform Material Law for High Strength Steels

Sinan Korkmaz

Uniform Material Law (UML) is a handy and user-friendly method since only the tensile strength data of the material is needed for estimation of the strain-life curve, in contrast to other methods, such as four-point correlation method, universal slopes met ...

On the influence of particle distribution and reverse loading on damage mechanisms of ductile steels

Roland Logé

During cold forming processes materials are subjected to non-monotonic complex multiaxial loadings. To obtain complex shapes at low temperature requires the use of particularly ductile materials. The damage behaviour of two ductile steels is studied here a ...

Evaluation of toughness by finite fracture mechanics from crack onset strain of brittle coatings on polymers

Yves Leterrier, Grégory Tornare

Crack onset strain measurements of a confined layer in tension provide the means for layer toughness estimation. The procedure can be simplified if steady-state conditions prevail starting from the commencement of crack propagation, an assumption frequentl ...

Fracture toughness behavior in the ductile-brittle transition region of the tempered martensitic Eurofer97 steel: Experiments and modeling

Philippe Spätig, Raul Alejandro Bonadé, Pablo Federico Mueller

The fracture toughness of the tempered martensitic stainless steel Eurofer97 has been experimentally characterized in the ductile-to-brittle transition (DBT) region with sub-sized compact tension specimens. The median fracture toughness–temperature curve i ...

Fracture toughness of TiAl alloys: A comparison of two gamma-a2 structures

Andreas Mortensen, Frédéric Diologent, Nicolas Vincent Barbi

Toughness measurements of a Ti-45Al-2N4u-2Nb + 0.8%vol TiB2 alloy with a. near fully lamellar microstructure and a Ti-46Al-8Nb alloy with a convoluted microstructure are performed at 650 degrees C under vacuum according to ASTM Standard E1820. Respective v ...

A probabilistic assessment of the effect of post-weld treatment on the fatigue performance of tubular truss bridges

Alain Nussbaumer, Scott Walbridge

In the design of tubular truss bridges, engineers have found the fatigue performance of the joints to be a critical aspect. In looking for ways to improve this performance, the use of residual stress-based post-weld treatments has been suggested. Although ...

Unzip instabilities: Straight to oscillatory transitions in the cutting of thin polymer sheets

Pedro Miguel Nunes Pereira de Almeida Reis, Ajay Kumar

We report an experimental investigation of the cutting of a thin brittle polymer sheet with a blunt tool. It was recently shown that the fracture path becomes oscillatory when the tool is much wider than the sheet thickness. Here we uncover two novel trans ...

Radiation damage in ferritic/martensitic steels for fusion reactors: a simulation point of view

Low activation ferritic/martensitic steels are good candidates for the future fusion reactors, for, relative to austenitic steels, their lower damage accumulation and moderate swelling under irradiation by the 14 MeV neutrons produced by the fusion reactio ...
