Experimental investigation on the mixed-mode fracture of rubber-toughened PMMA using essential work of fracture method

Autor: Farhang Abbasi, Naghdali Choupani, E. Haddadi

Publikováno v: Engineering Fracture Mechanics. 162:112-120

In order to fully achieve the benefits of rubber toughened polymers, a deep understanding of the fracture behavior; particularly under mixed-mode loading conditions is needed. In this investigation, the mixed-mode fracture of poly(methyl methacrylate

Modelling mixed-mode fracture in poly(methylmethacrylate) using peridynamics

Autor: Francesco Caimmi, Naghdali Choupani, Luca Andena, E. Haddadi, Claudia Marano

Publikováno v: Procedia Structural Integrity. 2:166-173

Peridynamics (Silling (2000)) is a non-local continuum theory that is particularly suited to handle discontinuities in the displacement field, such as those arising during fracture. Peridynamics prescribes that each material point interacts with all

Experimental and numerical investigation of fracture of ABS polymeric material for different sample's thickness using a new loading device

Autor: Abuzar Es'hagi Oskui, Naghdali Choupani, E. Haddadi

Publikováno v: Polymer Engineering & Science. 54:2086-2096

The fracture behavior of ABS (acrylonitrile butadiene styrene) polymeric material has been investigated under the full range of in-plane loading conditions using a new loading device to obtain more reliable results. Loading conditions from pure mode-

Preparation and Characterization of Expandable St/MMA Copolymers Produced by Suspension Polymerization

Autor: Kiyumars Jalili, Farhang Abbasi, E. Haddadi, M. Ghasemi, Malihe Nasiri

Publikováno v: Journal of Cellular Plastics. 45:197-224

Free radical suspension copolymerization of styrene (St) with methyl methacrylate (MMA) in the presence of n-pentane was investigated. The batch polymerization was performed in a stirred reactor via a two-stage process. First, free radical suspension
