A research group on forest products from School of Agriculture - Sao Paulo State University. Brazil developed a portable hardness tester for wood, which is based on a displacement transducer and an embedded electronic ...

Hardness is largely used in material specifications. Specifically for timber, Janka hardness is traditionally performed. More recently, international studies have reported the use of Brinell hardness for timber quality ...

Hardness is a property largely used in material specifications, mechanical and metallurgical research and quality control of several materials. Specifically for timber, Janka hardness is a simple, quick and easy test, with ...

More than 80% of the 29600 km of the Brazilian railroad mesh employs wooden sleepers. The problem of hard availability of native wood for this purpose leads to the alternative use of reforestation species to produce sleepers. ...

This study analyzes the effect of particle hardness on the transition from mild to severe abrasive wear. White cast iron with 1.9 wt% Cr with austenitic and martensitic matrices, white cast iron with 13.8 wt% Cr and 24.4 ...

The authors studied the CREEP of 5 amalgam alloys (1 conventional and 4 with high cooper) by the application os static load of 36 MPa in 478 mm specimens, 7 days old. After CREEP test, the samples were included in acrylic ...
