The purpose of this work is to explore the non-Fourier heat transport and fracture behaviours of an aluminium foam plate containing a central crack subjected to sudden hot thermal shocks by utilising the G-K model. The weight function methodology coupled with the superposition principle is adopted to address the mode-I fracture problem. Parametric investigations are conducted to examine the influences of thermal relaxation time, nonlocal length, and relative density of aluminium foams on the transient heat transfer and the dynamic fracture responses. The time lagging effect and the thermal nonlocal length scale are demonstrated to be critical factors governing the transient processes. The findings will facilitate an in-depth understanding and promote aluminium foam\u2019s applications as thermal insulation materials in extreme thermal conditions.<\/jats:p>","DOI":"10.3390\/ma19142933","type":"journal-article","created":{"date-parts":[[2026,7,8]],"date-time":"2026-07-08T16:16:18Z","timestamp":1783527378000},"page":"2933","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Transient Non-Fourier Fracture Analysis of a Central Crack in Aluminium Foams by Guyer\u2013Krumhansl Theory"],"prefix":"10.3390","volume":"19","author":[{"given":"Kunyang","family":"Cao","sequence":"first","affiliation":[{"name":"School of Intelligent Manufacturing, Henan Polytechnic, Zhengzhou 450046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiaqi","family":"Zong","sequence":"additional","affiliation":[{"name":"CCCC Mechanical & Electrical Engineering Co., Ltd., Beijing 101300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhijun","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Civil Engineering and Mechanics, Lanzhou University, Lanzhou 730000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0106-9638","authenticated-orcid":false,"given":"Zengtao","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, University of Alberta, Edmonton, AB T6G 1H9, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenzhi","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Civil Engineering and Mechanics, Lanzhou University, Lanzhou 730000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,8]]},"reference":[{"key":"ref_1","first-page":"3562","article-title":"Prediction of Mechanical Properties and Stress\u2013Strain Relation of Closed-Cell Aluminium Foam Under Compression Using Neural Network Models","volume":"18","author":"Dudzik","year":"2025","journal-title":"Materials"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Kunac, K., \u010catipovi\u0107, N., Antunovi\u0107, K., and Juri\u0107, D.
