This work deals with an experimental and numerical approach to determining the differed behavior of compressed wood elements subjected creep loading. An protocol is associated a mechanical model, whose purpose isolate effects from those shrinkage-swelling, while allowing for long duration test be conducted. The based on compression applied five wooden columns disposed in climatic room one year....

The construction of the future is moving in direction environmentally friendly materials and use various types industrial byproducts wastes. blast furnace slag (BFS) for production concrete one those alternatives. In this study, pastes concretes based on high-MgO BFS were alkali activated with 10% by weight sodium carbonate, silicate, a combination both. Heat treatment laboratory curing applied...

Creep damage is one of the serious problems for the high temperature industries and computational approach (such as continuum damage mechanics) has been developed and used, complementary to the experimental approach, to assist safe operation. However, there are no ready creep damage constitutive equations to be used for predicting the lifetime for this type of alloy, particularly for low stress...

Coal pillars from old mines undergo creep, a type of time?dependent deformation. Research on underground engineering stability coal has increasingly focused long?term strength as an important mechanical index the creep characteristics pillars. This study performed conventional triaxial compression and tests anthracite under different confining pressures. The law was studied according to test re...

conclusions the stereotactic brachytherapy for patients with circumscribed and relatively small size tumors appears to be a safe, feasible, and minimally-invasive treatment. results thirteen patients were male and 16 were female, with the median age of 29 years (range, 2.5 – 64 years). the median follow-up was 95 (range, 6 – 240) months. based on pignatti classification, 10 patients were at low...
