Nonlinear electric conductance of reinforced insulation can homogenize field distribution and suppress local distortion inside high-voltage direct current cable accessories. To achieve a significant nonlinear in ethylene–propylene–diene misch–polymere (EPDM) used for accessories, the inorganic micron crystal powder calcium copper titanate (CCTO) is synthesized by sol–gel method, which filled in...

Thermoplastic elastomers (TPEs), based in PP (Polypropylene) / EPDM (Ethylene Propylene Diene Monomer) have as purpose improving resistance and impact, aiming to a more comprehensive use automotive market, among edifications, construction packaging sectors, due their recyclability properties. is commodity, with high melting point, mechanical low density, posing balance between physical properti...

The main objective of the current research work is to explore effect nanosilica particles on compound EPDM/SBR-SiO2 (ethylene-propylene-diene monomer/styrene-butadiene rubber-nanosilica). composite EPDM/SBR with and without silane coupling agent was processed using an open mill mixer. are prepared in laboratory were used as reinforcing material rubber composites. cure characteristics, mechanica...

This study used ethylene-propylene diene monomers (EPDM), an elastomer, to develop foams incorporating clay as filler using simple compounding, chemical foaming, and peroxide-mediated light crosslinking methods. The low-temperature batch mixer was employed for compounding azodicarbonamide (ADC) a foaming agent, dicumyl peroxide (DCP) crosslinker, followed by compression molding sheet preparatio...

Well-Structured Transitions Systems (WSTS) constitute a generic class of infinite-state systems for which several properties like coverability remain decidable. The family of coverability languages that they generate is an appropriate criterium for measuring their expressiveness. Here we establish that Petri Data nets (PDNs) and Timed Petri nets (TdPNs), two powerful classes of WSTS are equival...

Abstract Working on quasi‐static phase‐field fracture modeling in nearly incompressible solids for crack propagation is a challenging task. To avoid arising locking effects therein, mixed form the solid displacement equation developed, resulting two unknowns: field and hydro‐static pressure variable. In order to fulfil an inf‐sup condition, stable Taylor‐Hood elements are employed displacement‐...
