A phenomenological material model is developed to understand the pseudo-ductile behavior of steel fiber reinforced high performance concrete (HPC) during failure. In that respect, an energy function formulated using additive composition a transversal isotropic elasto-plastic and phase-field representing individual fibers material, respectively. Comparing experimental data numerical results thre...

The endochronic theory, developed in the early seventies, allows the plastic behavior of materials to be represented by introducing the notion of intrinsic time. With different viewpoints, several authors discussed the relationship between this theory and the classical theory of plasticity. Two major differences are the presence of plastic strains during unloading phases and the absence of an e...

an energy based damage index based on a new nonlinear finite element (fe) approach applicable to rc structures subjected to cyclic, earthquake or monotonic loading is proposed. the proposed method is based on the evaluation of nonlinear local degradation of materials and taking into account of the pseudo-plastic hinge produced in the critical sections of the structure. a computer program is dev...

The objective of this study was to formulate sodium alginate based ophthalmic mucoadhesive system of gatifloxacin and its in vitro antibacterial potential on pathogenic microorganisms, Staphylococcus aureus and Escherichia coli. Sodium carboxymethylcellulose (NaCMC) was added to the formulations to enhance the gel bioadhesion properties. The prepared formulations were evaluated for their in vit...

Introduction. "See and treat" one-stop clinics (OSCs) are an advocated NHS initiative to modernise care, reducing cancer treatment waiting times. Little studied in plastic surgery, the existing evidence suggests that though they improve care, they are rarely implemented. We present our experience setting up a plastic surgery OSC for minor skin surgery and survey their use across the UK. Methods...

Details and elements of structures, which are made functionally heterogeneous materials have the property shape memory behave pseudo-elastically, may be under influence complex loads in process manufacturing operation. Uneven heating bodies combination with force factors can lead to large deformations material deformation processes. The existing models behavior such do not take into account non...

This article discusses the nonlinear behavior of corrugated packaging during compression. The model this is a load-displacement curve with an ascending branch, peak point and descending branch. In some cases, branch shows signs plastic transition and/or loss stability container walls. purpose work to predict into (or pseudo-plastic) state. condition unacceptable because there are residual defor...
