The 2011 International Conference on Smart Materials and Nanotechnology in Engineering (ICSMCE2011)

作者： Hu Qingchun Sha Wenjian Li Yanhui Wang Yongsheng School of Mechanical and Automotive Engineering South China University of Technology

An explicit nonlinear analysis was implemented to calculate buckling load and stress distribution, based on the Abaqus/Explicit computer programAccording to the numerically obtained results, we can optimize the structure of the pet bottle in order to increase the buckling loadMoreover, according to the stress contour of pet bottle obtained by Abaqus, plastic distribution of pet bottle was optimized in order to improve the pet material efficiency and reduce the weight of pet bottle, and which provides a new design ideas for lightweight design of the pet bottle.

Rapid economic growth and production patterns have increased plastic consumption,plastic waste generation,and environmental pollution burden on both land and water habitats across the *** use of pet(polyethylene terephthalate)bottles in packaging has increased tremendously and accounts for a significant proportion of the plastic waste generated in Nigeria,along with its environment and economic *** sustainable development goals of sustainable cities and communities,responsible consumption and production,ensure access to safe water and sanitation has necessitated the need for an efficient pet bottle waste management *** study analyzed the pet bottle system in Nigeria and proposes an integrated pet bottle model/system for sustainable waste management,resource conservation,improved environmental sanitation,and economic development in ***,the need for the adoption of a holistic and indigenous approach in the formulation of the national policy on plastic waste management is emphasized,as it will encourage the citizens’participation and financial investments in waste management.
