Abstract
Due to its geometric flexibility, the arbitrary straight-side quadrilateral plate structure is applied in various engineering practices. This article explores the nonlinear transient response of arbitrary straight-side quadrilateral plates under pulse load, in which the graphene platelets reinforced metal foams (GPLRMF) material is taken into account due to their advantages of light-weight, high-strength and long service. Firstly, considering thermal factor, the nonlinear transient response model of quadrilateral plates is established based on the first-order shear deformation theory (FSDT) and von-Kármán's nonlinearity, where the effect of viscoelastic foundation is included. Then, the irregular physical domain is transformed into a regular computational domain through the four-point mapping procedure. Subsequently, the nonlinear transient response solution of the quadrilateral plate is obtained through Galerkin discretization and Runge-Kutta method. The accuracy of the present formulation in predicting the nonlinear transient response behavior of quadrilateral plates is illustrated by the convergent analysis and comparative study. Through preliminary parametric research, the effects of material parameters, load parameters, temperature, and shape parameters on the transient response of quadrilateral plates subjected to pulse load are demonstrated.
期刊介绍:
Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses.
Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering.
The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
