Verbeeten, Wilco M.H. 573 500 0000-0001-7026-1642 Arnold-Bik, Rob J. ed949810-4c03-4ce6-9f4a-ad6907c2394a 500 Lorenzo Bañuelos, Miriam 326 500 2021-03-10T12:48:54Z 2021-03-10T12:48:54Z 2021-01 http://hdl.handle.net/10259/5641 10.3390/polym13010149 2073-4360 The strain-rate sensitivity of the yield stress for Acrylonitrile-Butadiene-Styrene (ABS) tensile samples processed via material extrusion additive manufacturing (ME-AM) was investigated. Such specimens show molecular orientation and interstitial voids that affect the mechanical properties. Apparent densities were measured to compensate for the interstitial voids. Three different printing speeds were used to generate ME-AM tensile test samples with different molecular orientation. Printing velocities influenced molecular orientation and stretch, as determined from thermal shrinkage measurements. Likewise, infill velocity affected the strain-rate dependence of the yield stress. The ABS material manifests thermorheollogically simple behavior that can correctly be described by an Eyring flow rule. The changing activation volume, as a result of a varying print velocity, scales linearly with the molecular orientation, as captured in an estimated processing-induced pre-strain. Therefore, it is suggested that ME-AM processed ABS shows a deformation-dependent activation volume. This paper can be seen as initial work that can help to improve quantitative predictive numerical tools for ME-AM, taking into account the effects that the processing step has on the mechanical properties. application/pdf eng MDPI Polymers.. 2021, V. 13, n. 1, 13010149 https://doi.org/10.3390/polym13010149 Atribución 4.0 Internacional http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess 3D printing ABS printing speed strain-rate dependent yield stress process-induced molecular orientation Eyring rate equation strain-dependent activation volume Resistencia de materiales Strength of materials Print velocity effects on strain-rate sensitivity of acrylonitrile-butadiene-styrene using material extrusion additive manufacturing info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Polymers 13 1 149 ORIGINAL Verbeeten-polymers-2021.pdf Verbeeten-polymers-2021.pdf application/pdf 5870710 https://riubu.ubu.es/bitstream/10259/5641/1/Verbeeten-polymers-2021.pdf 01a44a7273785e52e3a16f75e57f3d08 MD5 1 CC-LICENSE license_rdf license_rdf application/rdf+xml; charset=utf-8 908 https://riubu.ubu.es/bitstream/10259/5641/2/license_rdf 0175ea4a2d4caec4bbcc37e300941108 MD5 2 LICENSE license.txt license.txt text/plain; charset=utf-8 999 https://riubu.ubu.es/bitstream/10259/5641/3/license.txt b295bcbce42e2caabeb0c623d3860c06 MD5 3 THUMBNAIL Verbeeten-polymers-2021.pdf.jpg Verbeeten-polymers-2021.pdf.jpg IM Thumbnail image/jpeg 3560 https://riubu.ubu.es/bitstream/10259/5641/4/Verbeeten-polymers-2021.pdf.jpg cc4ba1122897dc9edf4e88b35768b763 MD5 4 TEXT Verbeeten-polymers-2021.pdf.txt Verbeeten-polymers-2021.pdf.txt Extracted text text/plain 68205 https://riubu.ubu.es/bitstream/10259/5641/5/Verbeeten-polymers-2021.pdf.txt 8646f9bdc7c7e09d833e2707b982446f MD5 5 10259/5641 oai:riubu.ubu.es:10259/5641 2021-11-02 13:04:45.758 Repositorio Institucional de la Universidad de Burgos bubrep@ubu.es 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
