Mechanical and laser impact effects on woven composites with hemp or glass fibres

Fabienne Touchard, Michel Boustie, Laurence Chocinski-Arnault, Pedro Pascual González, Laurent Berthe, Davi de Vasconcellos, Luigi Sorrentino, Pawel Malinowski, Wieslaw Ostachowicz

The purpose of this paper is to study the damage induced in “green” and synthetic composites under impact loading.

Failure progression resistance of a generic steel moment-resisting frame under beam-removal scenarios

Farshad Hashemi Rezvani, Behrouz Behnam, Hamid Reza Ronagh, M. Shahria Alam

The purpose of this paper is to determine the failure progression resistance of the steel moment-resisting frames subjected to various beam-removal scenarios after application of…

Design of repairable regular steel buildings with square plan based on seesaw motion of building structure and using DADAS dampers

Faezeh Nejati, Mahmood Hosseini, Amir Mahmoudzadeh

Almost design code is required for repairability of the buildings after a major earthquake. One such idea is “directed-damage design” (DDD), which means guiding the damage to some…

Ballistic-penetration resistance and flexural-stiffness optimization of a nacre-mimetic, B4C-reinforced, polyurea-matrix composite armor

Mica Grujicic, Jennifer Snipes, S. Ramaswami

The purpose of this paper is to model a nacre-like composite material, consisting of tablets and polyurea tablet/tablet interfaces, B₄C. This composite material is being…

Use of wavelets for damage diagnostics in truss structures

Hussain Altammar, Sudhir Kaul, Anoop K. Dhingra

Wavelets are being increasingly used for damage diagnostics. The purpose of this paper is to present an algorithm that uses the wavelet transform for detecting mixed-mode, also…

Influence of the thickness of intumescent paint in the position of steels (fire safety)

Harkaitz Garcia, María Victoria Biezma, Jesús Cuadrado, Eduardo Rojí

The purpose of this paper is to analyze a new structural design applied in industrial frames using two type of steels (S275 and fire resistant (FR)) with different mechanical…

Prognostic analysis of fastener joints in straight attachment lugs

L. Chikmath, B. Dattaguru

Many failures of aircraft structural components in the past were attributed to cracks emanating from joints, which are identified as the most critical locations. In cases using…

Dynamic modeling and finite element structural optimization of glass handling robot

Chuanping Zhang, Fei Yu, Honggang Duan, Yuan Chen

The purpose of this paper is to design a glass handling robot and conduct a finite element analysis and structural optimization to solve the automation handling problem of…
