Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

This study delves into the mechanical properties of 3D-printed Polylactic Acid (PLA), a biodegradable thermoplastic polyester derived from renewable resources. The research focuses on developing a visco-hyperelastic model to accurately predict PLA's behavior under various conditions. The study employs experimental data from tensile and relaxation tests to validate the model, ensuring its reliability. The results demonstrate a good correlation between the model's predictions and experimental observations, particularly in the early and intermediate stages of relaxation tests. The study also identifies key material parameters and Prony series constants that characterize PLA's rate-dependent behavior. This research provides valuable insights into the mechanical properties of 3D-printed PLA, offering a robust model for predicting its behavior in various applications.
