摘要:Abstract(#br)This paper proposes an efficient numerical method for solving the dynamic responses of one-dimensional and two-dimensional periodic structures. Efficiently solving a system of linear equations is a crucial issue for computation of the dynamic responses of large-scale...

摘要:Abstract(#br)Cracks often exist in composite structures, especially at the interface of two different materials. These cracks can significantly affect the load bearing capacity of the structure and lead to premature failure of the structure. In this paper, a novel element for mod...

摘要:Abstract(#br)Increasing demand in material and mechanical properties has led to production of complex composite structures. The composite structures, made of different materials, possess a variety of properties derived from each material. This has brought challenges in both analy...

摘要:Abstract(#br)The failure of structures made of multiple materials is often caused by bimaterial interface cracks. Due to the complex nature of the stress field around the interface crack tip, the faithful modeling of such cracks requires numerical methods with high accuracy ...

摘要:Abstract(#br)A novel singular finite element is presented to study cracked plates with arbitrary traction acting on crack surfaces. Firstly, the analytical solution around crack tips is determined using the symplectic dual approach. Subsequently, the solution is used to develop a...

摘要:Abstract(#br)This paper presents a numerical method for fatigue crack growth in the framework of finite element method, i.e. a new enriched element is presented in which only the analytical solutions around crack tips are used to describe the displacements and stresses fields. A ...

摘要:Abstract(#br)This paper presents a bridging research between a modeling methodology in quantum mechanics/relativity and elasticity. Using the symplectic method commonly applied in quantum mechanics and relativity, a new symplectic elasticity approach is developed for derivin...

摘要:Past researchers have treated the vibration problem of rectangular orthotropic Kirchhoff plates by using the semi-inverse method with trial functions which, however, do not always exist. In this study, free vibration and harmonic forced vibration are analysed using a unified meth...
