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 chapter delves into the computational analysis of the dynamic characteristics of 3D printed biocomposite sandwich beams with periodic cores. The study focuses on the use of polylactic acid (PLA) matrix and flax fiber reinforcement, known for their eco-friendliness and good mechanical properties. The research investigates the vibration attenuation properties of these beams, particularly the effect of incorporating a periodic core with viscoelastic material (VEM) elements. The study compares the vibrational responses of three beams: a solid PLA/flax fiber beam and two sandwich beams with different material ratios in their periodic cores. The results show that the periodic core effectively attenuates vibrations within specific frequency ranges, known as band-gaps. The location and bandwidth of these band-gaps can be modified by altering the material ratio within the periodic core cells. This study highlights the potential for designing biocomposite structures with customizable vibration attenuation performance, which could be particularly useful in industries such as transportation, where reducing vibrations and improving passenger comfort are key concerns.
