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 ...

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 ...

Structure et mécanismes de microdéformation de polymethylmethacrylates renforcés au choc

Laure Dupuits Lalande

Polymethylmethacrylate (PMMA) is used in many applications requiring good optical properties, resistance to ageing and resistance to UV irradiation, in spite of its relatively poor mechanical response to impact loading. In order to extend the range of appl ...

Static cyclic response of masonry walls retrofitted with fiber-reinforced polymers

Pierino Lestuzzi, Marc Badoux, Mohamed Elgawady

The behavior of seven one-half scale masonry specimens before and after retrofitting using fiber-reinforced polymer (FRP) is investigated. Four walls were built using one-half scale hollow clay masonry units and weak mortar to simulate walls built in centr ...

Bone fracture risk assessing method involves inserting test probe through periosteum and soft tissue on bone, so as to evaluate resistance of bone to microscopic fracture

Georg Fantner

NOVELTY - The test probe (100) is inserted through periosteum and/or soft tissue on a bone, such that the test probe contacts the bone. The test probe is inserted multiple times into same location of the bone, to create one or more microscopic fractures in ...

Charpy impact tests on martensitic/ferritic steels after irradiation in SINQ Target-3

Yong Dai

Charpy impact tests were performed on martensitic/ferritic (MF) steels T91, F82H, Optifer-V and Optimax-A/-C irradiated in SINQ Target-3 up to 7.5 dpa and 500 appm He in a temperature range of 120-195 degrees C. Results demonstrate that for all the four ki ...

Ductile-to-brittle transition of low activation ferritic-martensitic steels with respect to critical cracks promoting final brittle fracture

9-11 wt.%Cr ferritic-martensitic steels with fine carbide structures are considered as potential candidates for the blanket and first wall structures of fusion reactors. Charpy impact tests have been performed in the ductile-to-brittle transition temperatu ...

Investigation of notched composite wood-concrete connections

Julius Natterer

An initial stage of research on the feasibility of a composite concrete-wood commercial floors system is described. The floors are comprised of concrete placed atop a solid layer of dimension lumber. A notched shear key/anchor detail is used for interlayer ...

Mechanical spectroscopy of Al-Cu-Fe quasicrystalline coatings

Robert Schaller, Nadine Baluc

Since the bulk Al-Cu-Fe quasicrystals are extremely brittle below 700 K, a quasicrystalline coating deposited on a steel substrate by thermal spraying was used for mechanical spectroscopy measurements at temperatures in the range of 300-800 K. The internal ...
