| dc.description.abstract | With the advancement of modern technology, the variety of materials used
and the demands of product design have significantly increased and become more
complex. In terms of material development, scholars and experts are dedicated to
pursuing materials that are lighter, stronger, and more cost-effective. Product
design has also become increasingly intricate to meet the growing number of
external conditions and requirements. However, complex designs have
historically posed significant challenges and incurred substantial costs in
industrial manufacturing. To effectively overcome these difficulties, additive
manufacturing technology emerged. Over the past two decades, this technology
has flourished in various engineering fields, such as automotive, aerospace, and
biomedical industries, and has even been referred to as the Third Industrial
Revolution.
INGROWS PU, abbreviated as IPU, is a newly developed filament by Acme
Biotechnology. It shares similar properties with TPU (thermoplastic
polyurethane), a material commonly used in additive manufacturing, and belongs
to the category of thermoplastic materials. However, precise material parameters
for this filament are difficult to find in common literature, and it is unclear whether
different printing methods or even environmental factors might affect its
IV
properties and parameters. Therefore, this study aims to combine additive
manufacturing with IPU filament to investigate the mechanical properties of IPU
filament formation. The main approach will involve both experimental testing and
numerical simulation to examine the material′s behavior under stress and its
corresponding elastic and plastic characteristics. The experimental tests will be
conducted using a universal testing machine for tensile and compressive tests,
while the numerical analysis will employ the Material Point Method. Additionally,
this thesis will delve into various material parameters, such as the Young′s
modulus and the tangent modulus during the plastic stage.
In summary, the results of the mechanical tests and numerical analyses of the
IPU filament series can serve as important reference data for future product design
and development. | en_US |
