The accuracy and efficiency of the elements proposed by finite element method (FEM) considerably depend on the interpolating functions namely shape functions used to formulate the displacement field within the element. In the present study, novel functions, namely basic displacements functions (BDFs), are introduced and exploited for structural analysis of nanobeams using finite element method ...

Polyurea-urethanes are one of the polyurethane categories that causes better phase separation due to increasing the hard segment length and non-covalent interactions. In this research, hydroxyl-terminated polybutadiene based polyurea-urethanes have been synthesized via one-pot polymerization of triethanol amine triflouroborate comlex as cross-linker, isophoron diisocyanate as curing agent and v...

the dissipated energy from periodic deformation is regarded as the main reason for heat generation and temperature rise inside the tire domain. however, the mechanical behavior of rubber parts is highly temperature dependent. in most performed investigations, the influence of thermal effects on stress/ deformation fields of pneumatic tires is ignored and just temperature distribution is conside...

background: autoregulation of blood flow is a marvelous phenomenon balanc- ing blood supply and tissue demand. although many chemically-based explanations for this phenomenon have been proposed and some of them are commonly used today, biomechanical aspects of this phenomenon was neglected. the biomechanical aspect provides insights to us to model vessel diameter changes more precisely and comp...

owing to elastic and viscous characteristics embedded rubber compounds, the dissipated energy from periodic deformation is converted into heat generation and consequently, the tire may have different body temperatures for different operating conditions. in most performed investigations, just temperature distribution is considered and the mechanical behaviour of rubber parts which are highly tem...

an artificial neural network (ann) model is developed for the analysis, simulation, and prediction of the austenite reversion in the thermo-mechanical treatment of 304l austenitic stainless steel. the results of the ann model are in good agreement with the experimental data. the model is used to predict an appropriate annealing condition for austenite reversion through the martensite to austeni...
