In this study, we explore an a new crosslinker (bis-butyl succinate, BBS) with terminal alkyne group to react glycidyl azide polymer-based polyurethane (original PU) via “azide-alkyne” click reaction, which has supported enhancing mechanical properties and cross-link densities of modified PUs BBS. Besides, been designed synthesized successfully esterification reaction can incorporate the origin...

The purpose of this paper is to extend the Green-Naghdi-Rivlin balance of energy method to continua with microstructure. The key idea is to replace the group of Galilean transformations with the group of diffeomorphisms of the ambient space. A key advantage is that one obtains in a natural way all the needed balance laws on both the macro and micro levels along with two Doyle-Erickson formulas....

The sealing performance of the rubber packer is vital importance for subsea retractable connector, and cross-sectional shape one most important factors affecting it. compression distance increased by 19.54% utilizing established two-dimensional numerical model. In addition, a new parameter called anti-shoulder extrusion variable was defined in this paper. Shoulder will not occur when using as c...

Abstract The airless tires are developed to overcome a disadvantage of pneumatic tire which lost maneuverability caused flattening and blasting. finite element analysis (FEA) is an effective method for development have complex construction. material properties describe mechanical behavior each component very important yield accurate result. high order constitutive model usually obtains the accu...

The rheological and mechanical properties of elastomers are defined by their different networks: crosslink network the filler network. is influenced polymer structure. – particularly in case silica as depends on interaction between particles polymer. Liquid polymers can affect these networks lower molecular weight with certain types functional groups. goal present work to gain a better understa...
