Robust multiscale design of incompressible multi-materials under loading uncertainties
Engineering with Computers - Tập 38 - Trang 875-890 - 2021
Most of the multiscale topology optimization (TO) approaches, which have been proposed for multi-material designs, are based on the assumption of deterministic loads and the exclusion of uncertain quantities like positions, directions, and magnitudes of loads. This contribution deals with: (1) multiscale design; (2) multi-materials; (3) loading uncertainties; and (4) incompressible materials such ......
Prediction of building damage induced by tunnelling through an optimized artificial neural network
Engineering with Computers - Tập 35 - Trang 579-591 - 2018
Ground surface movement due to tunnelling in urban areas imposes strains to the adjacent buildings through distortion and rotation, and may consequently cause structural damage. The methods of building damage estimation are generally based on a two-stage procedure in which ground movement in the greenfield condition is estimated empirically, and then, a separate method based on structural mechanic......
Explosion damage analysis of concrete structure with bond-associated non-ordinary state-based peridynamics
Engineering with Computers - Tập 39 - Trang 607-624 - 2022
Peridynamics has unique advantages in solving discontinuity problems such as explosive damage of structures. To further promote the peridynamic models, numerical algorithms and applications, a bond-associated non-ordinary state-based peridynamics (BA-NOSB PD) approach embedded with the Johnson–Holmquist II (JH-2) constitutive is established to analyze the explosive damage and failure of concrete s......
Virtual prototyping of a car turn-signal switch using haptic feedback
Engineering with Computers - Tập 26 - Trang 99-110 - 2009
The present work describes the virtual prototyping procedure of car turn-signal switches using a dedicated haptic feedback system. Although turn-signal switches have mechanisms with simple geometry, simulating the “feeling” during its operation is still a challenge. In order to allow ergonomics designers to directly assess the comfort of operation, a dedicated haptic system was developed for repro......

Hierarchical data management for structural analysis
Engineering with Computers - Tập 1 - Trang 45-54 - 1985
The use of formal data bases management systems is becoming increasingly necessary in computer programs for structural engineering. This paper briefly reviews data base requirements and the organization of integrated computer program networks and identifies a need for hierarchical data base management in computer programs for structural analysis. The nature of the data hierarchy is illustrated wit......
A data management strategy to control design and manufacturing information
Engineering with Computers - Tập 7 - Trang 63-78 - 1991
This paper presents an information-based approach to integrate the parallel and serial functions that occur in a typical design and manufacturing environment. EMTRIS (Engineering and Manufacturing Technical Relational Information System), a relational data base application designed using ORACLE [1], was developed to cater to the engineering data needs of practicing designers and engineers working ......
Novel hybrid machine leaning model for predicting shear strength of reinforced concrete shear walls
Engineering with Computers - Tập 38 - Trang 3915-3926 - 2021
Accurate prediction of the ultimate shear capacity of reinforced concrete shear walls (RCSWs) is essential for robust design of buildings under seismic and wind loads. However, the shear capacity of RCSWs depends on multiple complex design variables characterized by diverse geometric and materials properties. Thus, a powerful modeling framework is required. In this paper, a hybrid artificial intel......
On the size-dependent bending and buckling of the partially covered laminated microplate
Engineering with Computers - Tập 39 - Trang 685-710 - 2022
The bending and buckling of the microcomponents show size dependency. The strain gradient elasticity theory is proposed to explain the size dependency. In this paper, we derive the theoretical relations among the modified strain gradient elasticity theory, the modified couple stress theory and the general strain gradient elasticity theory, and clarify the degradation relation. The general theory i......
