Dynamic stability analysis of porous functionally graded beams under hygro-thermal loading using nonlocal strain gradient integral model被引量：2
《Applied Mathematics and Mechanics(English Edition)》2023年第12期2071-2092,共22页Pei ZHANG P.SCHIAVONE Hai QING 
Project supported by the National Natural Science Foundation of China(No.12172169);the Natural Sciences and Engineering Research Council of Canada(No.NSERC RGPIN-2023-03227)。
We present a study on the dynamic stability of porous functionally graded(PFG)beams under hygro-thermal loading.The variations of the properties of the beams across the beam thicknesses are described by the power-law ...
