An accurate constitutive model is one of the basic aspects to ensure a precise simulation. This study presents an improved unified viscoplastic model to simulate the various behavior of P92 steel under low cycle fatigue (LCF) and creep fatigue interaction (CFI) loadings. In the proposed model, an accumulated inelastic strain dependent parameter is introduced into the nonlinear kinematic hardening rule to represent the evolutionary behavior of ...

Measurement technology based on structured light is a current research focus in the field of visual measurement and is widely applicable to various fields of industrial measurement. How to quickly and accurately locate and continuously track the rail head and rail waist region from dynamically changing laser fringe images remains a key issue to be solved in rail profile detection and analysis. An algorithm based on deep learning is proposed in ...

Coastal structures are crucial to protect the coastline from destructive impacts induced by sea wave attacks. Structure failures, erosion, and overtopping water should be prevented or minimized during extreme events for maximizing the efficiency of the structures. In this work, we numerically investigated various shapes of seawalls in terms of force exerted on structures and overtopping water under a variety of sea waves by using an open source ...

This study adapts the flexible characteristic of meshfree method in analyzing three-dimensional (3D) complex geometry structures, which are the interlocking concrete blocks of step seawall. The elastostatic behavior of the block is analysed by solving the Galerkin weak form formulation over local support domain. The 3D moving least square (MLS) approximation is applied to build the interpolation functions of unknowns. The pre-defined number of ...

This study aims to present a three-dimensional (3D) numerical solution for investigating the free vibration and buckling responses of annular plate, conical and cylindrical shell made of functionally graded (FG) porous rock materials. Isogeometric analysis (IGA) is utilized in order to develop the 3D numerical solution. Furthermore, the computational package is developed using C# Programming, which is an object-oriented programming language. The ...

This paper concerns a comparative study assessing the impact of various mechanical surface treatment methods on the strength of adhesively bonded joints. The surface treatment methods used were glass-bead blasting and steel shot blasting. The joints used sheet components of S235JR steel, bonded with one of two epoxy adhesives. Several configurations of adhesive joints were tested, based on specific blasting medium variants. The study included ...
