A novel multiscale cohesive approach that enables prediction of the macroscopic properties of heterogeneous thin layers is presented. The proposed multiscale model relies on the Hill’s energy equivalence lemma, implemented in the computational homogenization scheme, to couple the microand macro-scales and allows to relate the homogenized cohesive law used to model the failure of the adhesive la...

The coupled damage/plasticity model for meso-level which is ply-level in case of Uni-Directional (UD) Fiber Reinforced Polymers (FRPs) is implemented. The mathematical formulations, particularly the plasticity part, are discussed in a comprehensive manner. The plastic potential is defined in effective stress space and the damage evolution is based on the theory of irreversible thermodynamics. T...

normal 0 false false false en-us x-none ar-sa background: cisplatin (cis-diamminedichloroplatinum ii; cp) is used widely as an antitumor drug in clinics, but is accompanied with renal toxicity. cisplatin induced nephrotoxicity consists of change in kidney weight, histological changes in kidney and increase in serum creatinine (cr) and blood urea nitrogen (bun). this study was designed to find o...

This work focuses on moisture effects mechanical properties of GFRP-balsa sandwich structure experimentally and numerically. Firstly, relationships between Moisture Content (MC) Acoustic Emission (AE) wave velocity have been demonstrated by Hsu-Nielsen tests during the water immersion tests. And then, a new methodology was proposed to predict elastic modulus skin wet based relationship MC, AE m...

The applicability of both prediction methods for low-cycle fatigue life powder superalloy based on the Manson-Coffin equation and damage mechanics were addressed. Both models evaluated by experimental data FGH96 with non-destructive standard parts those inclusions. Due to characteristics high strength low plasticity FGH96, errors in calculating plastic strain amplitude deviate severely outcomes...
