Verbeeten, Wilco M.H. 573 500 0000-0001-7026-1642 Lorenzo Bañuelos, Miriam 326 500 Saiz Ortiz, Rubén b23db867-0a6b-481d-a192-5bae32a2829f 500 González, Rodrigo 25038af5-967f-4fca-bc9a-4a3245d204ee 500 2021-03-12T09:23:36Z 2021-03-12T09:23:36Z 2020 1355-2546 http://hdl.handle.net/10259/5642 10.1108/RPJ-12-2019-0317 Purpose – The purpose of the present paper is to quantify and analyze the strain-rate dependence of the yield stress for both unfilled acrylonitrilebutadiene- styrene (ABS) and short carbon fiber-reinforced ABS (CF-ABS) materials, fabricated via material extrusion additive manufacturing (MEAM). Two distinct and opposite infill orientation angles were used to attain anisotropy effects. Design/methodology/approach – Tensile test samples were printed with two different infill orientation angles. Uniaxial tensile tests were performed at five different constant linear strain rates. Apparent densities were measured to compensate for the voided structure. Scanning electron microscope fractography images were analyzed. An Eyring-type flow rule was evaluated for predicting the strain-rate-dependent yield stress. Findings – Anisotropy was detected not only for the yield stresses but also for its strain-rate dependence. The short carbon fiber-filled material exhibited higher anisotropy than neat ABS material using the same ME-AM processing parameters. It seems that fiber and molecular orientation influence the strain-rate dependence. The Eyring-type flow rule can adequately describe the yield kinetics of ME-AM components, showing thermorheologically simple behavior. Originality/value – A polymer’s viscoelastic behavior is paramount to be able to predict a component’s ultimate failure behavior. The results in this manuscript are important initial findings that can help to further develop predictive numerical tools for ME-AM technology. This is especially relevant because of the inherent anisotropy that ME-AM polymer components show. Furthermore, short carbon fiber-filled ABS enhanced anisotropy effects during ME-AM, which have not been measured previously. application/pdf eng Emerald Rapid Prototyping Journal. 2020, V. 26, n. 10. p. 1701–1712 http://dx.doi.org/10.1108/RPJ-12-2019-0317 ABS material Anisotropic strain-rate-dependent yield stress Eyring rate equation Fused filament fabrication (FFF) Infill orientation Polymer matrix composites (PMC) Apparent density Resistencia de materiales Strength of materials Strain-rate-dependent properties of short carbon fiber-reinforced acrylonitrile-butadiene-styrene using material extrusion additive manufacturing info:eu-repo/semantics/article info:eu-repo/semantics/submittedVersion info:eu-repo/semantics/openAccess Rapid Prototyping Journal 26 10 1701 1712 ORIGINAL Verbeeten-rpj_2020.pdf Verbeeten-rpj_2020.pdf application/pdf 6584277 https://riubu.ubu.es/bitstream/10259/5642/1/Verbeeten-rpj_2020.pdf 143c2d6d22aac69fb774e26c9ab3e2b7 MD5 1 LICENSE license.txt license.txt text/plain; charset=utf-8 999 https://riubu.ubu.es/bitstream/10259/5642/2/license.txt b295bcbce42e2caabeb0c623d3860c06 MD5 2 THUMBNAIL Verbeeten-rpj_2020.pdf.jpg Verbeeten-rpj_2020.pdf.jpg IM Thumbnail image/jpeg 3679 https://riubu.ubu.es/bitstream/10259/5642/3/Verbeeten-rpj_2020.pdf.jpg df875ba4d824b6982881c4861a877376 MD5 3 TEXT Verbeeten-rpj_2020.pdf.txt Verbeeten-rpj_2020.pdf.txt Extracted text text/plain 60854 https://riubu.ubu.es/bitstream/10259/5642/4/Verbeeten-rpj_2020.pdf.txt 9fbdf4f8e656d620c6541bc35ed8f2cc MD5 4 10259/5642 oai:riubu.ubu.es:10259/5642 2021-11-02 13:04:45.069 Repositorio Institucional de la Universidad de Burgos bubrep@ubu.es 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
