On the development of plastic hinges in rigid-plastic beams

On the analysis of pure bending of rigid-plastic beams in strain-gradient plasticity

The complete stress field, including the microstress, the moment-stress, and the line forces are derived for the pure bending of a rigid-plastic beam of rectangular cross-section in the model of strain-gradient plasticity. The workless spherical parts of the microstress and the moment-stress tensors are incorporated in the analysis. Their determination is shown to be of importance for the fulfi...

The Role of Plastic Surgeons in Advancing Development Global

In September 2015, the international community came together to agree on the 2030 Agenda for Sustainable Development, a plan of action for people, the planet, and prosperity. Ambitious and far-reaching as they are, they are built on three keystones: the elimination of extreme poverty, fighting climate change, and a commitment to fighting injustice and inequality. Critical to the achievement of ...

A variational principle for plastic hinges in a beam

We focus the minimization of 1D free discontinuity problem with second order energy dependent on jump integrals but not on the cardinality of the discontinuity set, in the framework of L∞ load. The related energies are not lower semi continuous in BH. Nevertheless we show that if a safe load condition is fulfilled then minimizers exist and they belong actually to SBH, say their second derivativ...

A note on the derivation of rigid-plastic models

the impact of morphological awareness on the vocabulary development of the iranian efl students

this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
