Abstract A Problem Solving Environment for the finite element method (FEM-PSE) is an application system to support users pursuing a career in the finite element analysis (FEA). There are two types of users associated with the FEA. One is analysis-user who uses application software of the FEM and the other is development-user who develops application software of the FEM. We used an abstraction t...

In this paper, we first review the impact of the powerful finite element method (FEM) in structural engineering, and then address the shortcomings of FEM as a tool for riskbased decision making and incomplete-data-based failure analysis. To illustrate the main shortcoming of FEM, i.e., the computational results are point estimates based on “deterministic” models with equations containing mean v...

an aircraft wing needs to display different mechanical behavior in different directions. 1- stiffness in the spanwise (transverse to the corrugation) direction which enables the aerodynamic and inertial loads to be carried. 2- compliance in the chordwise (corrugation) direction which would allow shape changes and increases in surface area; whereas a corrugated sheet due to their special geometr...

Advancements in high-performance computing and in nonlinear dynamic structural simulation software such as ABAQUS have made it possible to virtually test potential designs prior to building and testing expensive prototypes. These tools alone, however, still require an engineer to develop a design based on intuition and numerous time-consuming and error-prone iterations. The next level of advanc...

The adequacy of timber joints determines how much load it can sustain, commonly called load-carrying capacity. European Yield Model (EYM), also known as Johansen yield theory, has been widely adopted in the design for predicting In EC5, pulling out capacity is 'rope effect' and becomes one parameter that governs a dowel-type connection. Due to high cost preparing specimen, computer modelling al...

using computation software to simulate fracture behaviors of structures can shorten the time to estimate safety of engineering structures and reduce a lot of cost of experiment. However three dimensional numerical simulation for fracture process is a challenging issue, because the convergence and accuracy are not easily obtained and high computational cost is generated. In this paper, three new...

This study aimed to investigate the precast reinforced concrete beam-to-column joints behaviors through replaceable damper under cyclic loading. The specimens have been embedded with steel reinforcement and specially shaped connectors. After application of loading, energy dissipation part has acted very well increased bearing capacity specimens. beam–to–column were designed analyzed compare (RC...

In the far north, low temperatures and atmospheric icing are a major danger for safe operation of wind turbines. It can cause several problems in fatigue loads, balance rotor aerodynamics. With aim improving rigidity turbine blade, composite materials currently being used. A numerical work aims to evaluate effect ice on blades determine most adequate material under conditions. Different thickne...

The continuous and synchronous calibration process for straightness roundness of LSAW (longitudinally submerged arc welding, LSAW) pipes with three rollers is a bidirectional reciprocating bending process. It includes both axial circumferential directions. particularly important to reveal the deformation mechanism, which provides theoretical support be applied actual production. Based on this, ...
