The influence of the voids generated by LECA particles on the syntactic composite samples density and mechanical behavior is characterized by quasi-static uniaxial compression. It is shown that smaller particles generate higher relative densities and a reduction in the value of densification strain. The use of larger particle diameter promotes an increase in yield strength and a more stable plateau region of the stress\u2013strain curve, leading to higher values of crushing energy absorption. The influence of the internal structure on these experimental results is correlated with elasto-plastic numerical simulations, and it is suggested that a small mismatch in LECA particle diameter is advantageous for enhancing mechanical properties.<\/jats:p>","DOI":"10.3390\/jcs2040064","type":"journal-article","created":{"date-parts":[[2018,11,1]],"date-time":"2018-11-01T11:31:47Z","timestamp":1541071907000},"page":"64","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Effect of Internal Structure in the Compression Behavior of Casted Al\/LECA Composite Foams"],"prefix":"10.3390","volume":"2","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1121-6793","authenticated-orcid":false,"given":"H.","family":"Puga","sequence":"first","affiliation":[{"name":"CMEMS-UMinho, University of Minho, Campus Azurem, 4800-058 Guimaraes, Portugal"}]},{"given":"Vitor H.","family":"Carneiro","sequence":"additional","affiliation":[{"name":"MEtRiCS-UMinho, University of Minho, Campus Azurem, 4800-058 Guimaraes, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7828-2912","authenticated-orcid":false,"given":"Joaquim","family":"Barbosa","sequence":"additional","affiliation":[{"name":"CMEMS-UMinho, University of Minho, Campus Azurem, 4800-058 Guimaraes, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,1]]},"reference":[{"key":"ref_1","unstructured":"Meller, M.A. (1926).
