Dr. Sulaiman, S. Edi Syams, Zainudin Khalina, Abdan, Dr. sapuan@upm.edu.my Lignocellulosic Stress variation Residual stress Link to publisher's homepage at http://www.journals.elsevier.com In this paper, a numerical analysis of in-cavity residual stress formation in the thin-walled parts of injection-moulded parts is presented by considering the residual stresses produced during the post-filling stage. Injection moulding of shallow thin-walled parts with a thickness of 0.7 mm was performed using lignocellulosic polymer composites (PP + 50 wt% wood), and the parts have been systematically investigated using simulation results from Autodesk MoldFlow Insight® software. In-cavity residual stresses constitute the primary stage for analysis because of the need to control the quality of moulded parts to prevent problems with shrinkage and warpage. The analysis showed that the cooling times and packing times had a less significant effect; nevertheless, the optimal levels that are required to be used in the moulding process for thin-walled parts yielded better results. The in-cavity residual stress results show that the stress variation across the thickness exhibits a high tensile stress at the part surface, which changes to a low tensile stress peak value close to the surface, with the core region experiencing a parabolic tensile stress peak. The optimum parameter ranges for obtaining the minimum in-cavity residual stresses are as follows: a mould temperature of 40–45 °C, a cooling time of 20–30 s, a packing pressure of 0.85Pinject, and a packing time of 15–20 s. 2014-06-15T14:06:48Z 2014-06-15T14:06:48Z 2014-03 Article Materials & Design, vol.55, 2014, pages 381–386 0261-3069 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35524 http://www.sciencedirect.com/science/article/pii/S0261306913008935 10.1016/j.matdes.2013.09.041 en Elsevier
