Journal ArticleDOI
Extended PDMS stiffness range for flexible systems
Rian Seghir,Steve Arscott +1 more
TL;DR: In this paper, the stiffness tunability of polydimethylsiloxane (PDMS) was investigated by varying the hardening agent to PDMS base ratio over 19:1 to 2:1, and using two extreme curing processes, i.e. 120min at 100°C and 2 days at 165°C.
Journal ArticleDOI
Controlled mud-crack patterning and self-organized cracking of polydimethylsiloxane elastomer surfaces.
Rian Seghir,Steve Arscott +1 more
TL;DR: An original and simple method to produce unique, localized and controllable self-organised patterns on elastomeric films using oxygen plasma, which indicates a level ofSelf-organization in the structuring and layout of the features.
Journal ArticleDOI
Influence of pores on crack initiation in monotonic tensile and cyclic loadings in lost foam casting A319 alloy by using 3D in-situ analysis
Long Wang,Nathalie Limodin,Ahmed El Bartali,Jean-François Witz,Rian Seghir,Jean-Yves Buffiere,Eric Charkaluk +6 more
TL;DR: In this article, the influence of lost foam casting microstructure on crack initiation in monotonic and cyclic tensile loadings was investigated using X-ray computed tomography (CT).
Journal ArticleDOI
An open-source Abaqus implementation of the phase-field method to study the effect of plasticity on the instantaneous fracture toughness in dynamic crack propagation
TL;DR: In this article, the authors investigated the effect of plasticity on dynamic fracture propagation and observed the increment of the instantaneous dynamic stress intensity factor during the acceleration stage of the crack without introducing a rate dependent critical fracture energy.
Journal ArticleDOI
Damage Investigation in A319 Aluminium Alloy by X-ray Tomography and Digital Volume Correlation during In Situ High-Temperature Fatigue Tests
Nora Dahdah,Nathalie Limodin,A. El Bartali,Jean-François Witz,Rian Seghir,Eric Charkaluk,Jean-Yves Buffiere +6 more
TL;DR: In this paper, the authors analyzed the strain field heterogeneity in an aluminium alloy subjected to low-cycle fatigue at high temperature and showed the importance of hard intermetallic phases in the crack propagation.
