PhD positions available at Polytechnique Montréal and McGill universities on shot peening with 5 aerospace companies

Ecole Polytechnique and McGill are seeking two PhD candidates for a large project aiming at understanding the effects of shot peening on the fatigue lives of aerospace components. The project involves 8 PhD students that will be working in close collaboration. The project is co-funded by the Canadian goverment and 5 leading aerospace companies located in Montréal. Some projects involve internships at these companies.

We are seeking two students for the following projects:

 

Case Studies in Engineering Failure Analysis - New Journal welcoming submissions!

We are very pleased to announce the launch of a new journal in the field of mechanical engineering, Case Studies in Engineering Failure Analysis. This journal provides a forum for the rapid publication of short, structured Case Studies in Engineering Failure Analysis and related Short Communications and will provide an essential compendium of case studies for practitioners in the field of engineering failure analysis and others who are interested in the ways in which components fail.

Managing Stress Waves over Multi-frequencies and Micro-architectural Design of Materials - Part 1, 2 and 3 available

Watch the 3-part video seminar where Sia Nemat-Nasser discusses certain basic issues regarding systematic homogenization techniques to extract the frequency‐dependent dynamic properties of microstructurally periodic composites, illustrating the results in terms of measureable and experimentally verifiable quantities.  To watch the videos, go to http://tinyurl.com/caudkwp

Tech Brief: Composite Winglet Optimization for Reliability and Robustness

A new tech brief was recently released on composite optimization. See below for additional information:  

Composite materials offer the potential for structures of lighter weight than their metallic counterparts. The stiffness and strength of a laminated composite structure depends directly on the ply stacking sequence. A design process that includes the effects of manufacturing tolerances and variability in lamina properties will allow for a more reliable and robust structure.

Water Landing of Space Flight Re-entry Vehicles Using Abaqus/Explicit

Space flight re-entry vehicles need to withstand heavy impact upon landing and it is critical for engineers to understand the effects on the vehicle and the crew to ensure the safety of the mission.  In order to gain this insight, engineers need to be able to model both the space craft structure and the landing medium such as water, sand, clay, etc.

Water Landing of Space Flight Re-entry Vehicles Using Abaqus/Explicit

Space flight re-entry vehicles impart highly dynamic loads on the crew and/or payload during a water landing. To understand the behavior of the vehicle/payload system as it makes impact, a predictive framework that can simultaneously model the structure, the highly deformable landing medium (water or soil), and their interaction is required. The coupled Eulerian-Lagrangian (CEL) method in Abaqus/Explicit provides the means for capturing these complex physical phenomena.

Simulation of the Quasi-static Crushing of a Fabric Composite Plate

Composite structures often have a higher capacity for ab-sorbing energy than their metal counterparts. The crush-ing behavior of composite materials is complex, and the inclusion of composite components in vehicles for crash protection can necessitate expensive experimental test-ing. The ability to computationally simulate the crushing response of composite structures can significantly shorten the product development cycle and reduce cost in the aerospace, automotive, and railway industries.

Bird Strike Simulation on a Wing Slat using Abaqus/Explicit

Bird strikes cost the United States aviation industry tens of millions of dollars annually in aircraft damage and schedule delays. Increasing the ability of the aircraft to resist bird strike induced damage is one part of an overall approach to mitigating this expense [1]. Experimental bird strike testing is part of the certification process for certain aircraft component designs. If a subset of the tests can be replaced with computational simula-tion, the cost of the prototype testing can be reduced.

Aircraft Landing Gear Simulation using Abaqus/Explicit

A mechanical system, such as aircraft landing gear, can have a large number of parts that interact in a complex nonlinear fashion. The challenge of simulating such a sys-tem lies not only in capturing the correct physical behavior but in using efficient analysis techniques. Different levels of modeling abstraction may be appropriate for different stages of the design process. Initial sizing and kinematics can be studied with a partially rigid representation, while final designs are more often analyzed with fully meshed flexible geometry.

Projectile Impact on a Carbon Fiber Reinforced Plate

Composite materials offer significant design advantages in the aerospace industry. High strength and light weight are the two most attractive features for aircraft and space vehicle designs. However, their complex material behav-ior makes analysis of these structures a significant chal-lenge, particularly in a high speed impact event. The ad-vanced composite modeling and industry leading simula-tion capabilities of Abaqus/Explicit make analysis of these challenging materials straightforward and allow accurate prediction of ballistic limit, damage and failure.

Buckling and Fracture Analysis of Composite Skin/Stringer Panel Using VCCT

The use of composite materials in the aerospace industry is increasing. Composite materials offer a relatively high strength-to-weight ratio as well as the ability to create large, integrated structures. One composite component can replace 10 or more traditional metal parts, which can dramatically reduce manufacturing time and cost.
