In the present research, finite element solutions of thermal post-buckling load-bearing strength of functionally graded (FG) sandwich shell structures are reported by adopting a higher-order shear deformation type kinematics. For the numerical calculation, nine nodes are considered for each element. A specialized MATLAB code is developed incorporating the present mathematical model to evaluate the numerical buckling temperature. The Green–Lagrange nonlinear strain is adopted for the formulation ...

We study a forced convective three-dimensional flow and heat transfer in the porous medium. Temperatures of the fluid and solid phases are not identical leading to local thermal non-equilibrium (LTNE) conditions, and hence we require two heat transport equations: one for each phase. This model arises when a hot (cold) fluid flows through a relatively cold (hot) porous medium. This situation usually appears in geothermal and chemical engineering applications. The flows outside the boundary layers...

The application of multi-objective optimization algorithms in the field of structural damage identification has gained increasing attention in the past few years. Nevertheless, their application to the damage detection problems of composite structures is still very limited. In this regard, the article presents the first attempt to implement a multi-objective optimization framework based on multi-objective cuckoo search (MOCS) algorithm for identifying the locations and extent of multi-damages in...

This paper, based on an extended bi-directional evolutionary structural optimization method, proposes a design approach to minimize the maximum von Mises stress of continuum structures subject to both material use and casting constraints. The stress singularity phenomenon is avoided naturally by the technique of discrete variable of the bi-directional evolutionary structural optimization method. The maximum von Mises stress is approximated by the global p-norm stress aggregation approach, and th...

Only by balancing the exploitation and exploration ability of the algorithm can the swarm intelligence optimization algorithm have better performance. Therefore, hybrid algorithms have attracted more and more attention in the field of optimization algorithms. Its performance is determined by both intelligent algorithm and constraint-handling technique when the hybrid intelligent algorithm is used to solve constrained optimization problems. In this paper, the original constrained optimization pro...

Harris Hawk’s Optimizer (HHO) is a recently developed meta-heuristics search algorithm with inherent capability to explore global minima and maxima. However, the local search of the basic HHO algorithm is sluggish and has slow convergence rate due to its poor exploitation capability. In the present work, exploration and exploitation phase of HHO have been improved using a chaotic variant of the present optimizer. The proposed chaotic variant has been simulated and tested for 23 standard test fun...

The derivation of nonlocal strong forms for many physical problems remains cumbersome in traditional methods. In this paper, we apply the variational principle/weighted residual method based on nonlocal operator method for the derivation of nonlocal forms for elasticity, thin plate, gradient elasticity, electro-magneto-elasticity and phase-field fracture method. The nonlocal governing equations are expressed as an integral form on support and dual-support. The first example shows that the nonloc...

As a new nature-inspired swarm intelligence optimizer, squirrel search algorithm (SSA) has shown potential to solve several real-world problems, but for some complex problems, it still suffers from degraded performance. In this paper, a hybrid squirrel search algorithm (NOSSA) combined with optimal neighborhood update and quasi-opposition learning strategies is proposed to overcome the drawback of population update guided only by leading individuals in SSA. NOSSA adopts a stochastic optimal neig...

This paper aims to propose a systematic numerical modelling framework to quantify the effects of phase change material (PCM) on the early-stage rutting performance of asphalt concrete pavement. Materials, structures, environments and traffic loads of the pavement system were characterized, modelled and implemented into a finite element model. Hourly variations in environmental and traffic conditions for the pavement structure were considered. The temperature profile in the pavement was calculate...
