Journal ArticleDOI
Influence of chain extender on mechanical, thermal and morphological properties of blown films of PLA/PBAT blends
TL;DR: In this article, a multifunctional epoxy chain extender, Joncryl ADR 4368, was used as compatibilizer to change the morphology and mechanical properties of blown films.
Journal ArticleDOI
Case study and analysis of a fatigue failure in a THA stem
Sandro Griza,Silvando Vieira dos Santos,Marcelo Massayoshi Ueki,Fabiano Bertoni,Telmo Roberto Strohaecker +4 more
TL;DR: In this paper, the authors present a case of a collared, polished and cemented hip stem which presented premature fracture due to the "cantilever beam" effect.
Journal ArticleDOI
Rheology, Mechanical Properties and Morphology of Poly(lactic acid)/Ethylene Vinyl Acetate Blends
Pankaj Agrawal,Aylanna P. M. Araújo,Jéssica C. C. Lima,Shirley N. Cavalcanti,Daniel M. G. Freitas,Giselly M. G. Farias,Marcelo Massayoshi Ueki,Tomas Jefferson Alves de Mélo +7 more
TL;DR: In this article, the effect of ethylene vinyl acetate (EVA) content on the rheology, mechanical properties, and morphology of poly (lactic acid) (PLA)/EVA blends was investigated.
Journal ArticleDOI
Thermally induced strains and total shrinkage of the polymethyl-methacrylate cement in simplified models of total hip arthroplasty.
Sandro Griza,Marcelo Massayoshi Ueki,Dárcio H.G. Souza,André Cervieri,Telmo Roberto Strohaecker +4 more
TL;DR: An evaluation of transient and stabilized strains in the cement mantle during polymerization was carried out in simplified cemented total hip arthroplasty (THA) model and indicated that positive strain peaks found during the exothermic stage of polymerization have the potential to produce pre-loading cracking.
Journal ArticleDOI
Effect of the chemical structure on the linear viscoelastic behavior of acrylic and styrenic polymer blends
Juciklécia da Silva Reinaldo,Laurenice Martins Pereira,Erik dos Santos Silva,Marcelo Massayoshi Ueki,Edson N. Ito +4 more
TL;DR: In this article, the influence of chemical structure on the linear viscoelastic rheological behavior of polymer blends comprising acrylic and styrenic polymers was investigated using Fourier transform infrared spectroscopy.
