| Abstract | In this paper, the dynamic stability and bifurcation phenomenon for a class of isotropic functionally graded plates including power-law, sigmoid and exponential function under lateral stochastic loads are studied and compared. Due to the existence of random loads, both the behavior investigation and response analysis are not conventional deterministic methods. So, the instability region and border curves of bifurcation are evaluated via a probability density function of the response. The latter is computed from a completely exact solution of the Fokker–Planck–Kolmogorov equation. The three-dimensional instability region and the border curves of bifurcation are drawn with respect to material parameter, in-plane forces and the mean value of lateral forces. To generalize the results, all the parameters are transformed to some suitable nondimensional variables, and then, the effects of all mentioned parameters on the dynamic stability are completely discussed and compared. Finally, the analytic results are validated by drawing numeric bifurcation diagrams for the nondimensional deflections of plates. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
