This work focuses on the reinforcement of polyoxymethylene (POM) by nanosilica particles (NS) in order to increase flexural strength and hardness POM matrix. Thermo - mechanical properties POM/NS nanocomposite were investigated using dynamic thermal analysis (DMTA).

thermoplastic polyurethane (tpu)/clay nanocomposites were prepared via a melt-compounding method using ester type tpu and two different modified organoclays (cloisite 30b and cloisite 15a) in different contents. the effects of the chemical structure and content of the nanoclays on the thermal degradation and mechanical properties of tpu were also investigated. the effect of structural modificat...

This paper focuses on the non-linear responses in thin cylindrical structures subjected to combined mechanical and thermal loads. The coupling effects of mechanical deformation and temperature in the material are considered through the development of a thermo-elasto-viscoplastic constitutive model at finite strain. A meshfree Galerkin approach is used to discretize the weak forms of the energy ...

Lately, renewable resources received great attention in the macromolecular compounds area, regarding the design of the monomers and polymers with different applications. In this study the capacity of several modified vegetable oil-based monomers to build competitive hybrid networks was investigate, taking into account thermal and mechanical behavior of the designed materials. In order to synthe...

Rubber seed shell (RSS) was modified by grafting treatment using glycidyl methacrylate (GMA) at various concentrations. The RSS was then used to reinforce high-density polyethylene (HDPE). The effects of modification on the mechanical, water absorption, and thermal properties of the RSS/HDPE composites were studied using a mechanical testing instrument, weighing method, Vicat softening temperat...

In this paper, a fast and efficient tool for predicting a set of physical and mechanical composite properties such as thermal expansion coefficients, thermal and electrical conductivity, stiffness, and thermal residual stress is developed based on the analysis of a representative volume of ZrO2-based composite. Such an analysis allows an engineer to assess the mechanical and physical properties...

In this paper, the mechanical behavior of three-phase inhomogeneous materials is modeled using the meso-scale model with lattice beams for static and dynamic analyses. The Timoshenko beam theory is applied instead of the classical Euler-Bernoulli beam theory and the mechanical properties of lattice beam connection are derived based on the continuum medium using the non-local continuum theory. T...

linear low density polyethylene (lldpe) was blended with esterified styrene-maleic anhydride (esma) and its physical and mechanical properties were studied. styrene-maleic anhydride (sma) copolymer was synthesized by precipitation reaction. then, sma was esterified by 1-decanol in methylethyl ketone solvent. from the ftir spectrum of esma it is evident that the corresponding peaks of anhydride ...

This paper presents finite element analysis (FEA) of a coated and uncoated cylinder heads of a diesel engine to examine the distribution of temperature and stress. A thermal barrier coating system was applied on the combustion chamber of the cylinder heads, consists of two-layer systems: a ceramic top coat (TC), made of yttria stabilized zirconia (YSZ), ZrO2-8%Y2O3 and also a metallic bond coat...
