1. Analysis of a car door subjected to side pole impact
Abstract The results of a study on the response of a side impact beam located in a car door to impact loading is presented. The side impact beam is situated in both the front and rear side doors of a vehicle between the inner and outer shells to minimise intrusion into the passenger compartment during a collision whilst absorbing as much impact energy as pos

2. Assessing the crashworthiness of a vehicle seat for rear and frontal impacts
Abstract A vehicle seat represents an automotive passive system because it limits the damage caused to passengers in the events of an accident or a crash. This way, the present work intends to evaluate the safety of an anchorage mechanism of a frontal vehicle driver seat considering two hazardous situations rear and frontal impacts. Performing a nonlinear FE

3. Analytical determination of the critical impact location for wing leading edge under birdstrike
Abstract The wing leading edge is one of the aircraft structures which are vulnerable to birdstrike. Therefore, Federal Aviation Regulation has clear requirements of anti-birdstrike performance for wing leading edge. However, the impact location is not specified in aviation regulation. The forefront of the wing leading edge is selected as a critical location

4. Sensitivity analysis and optimization for occupant safety in automotive frontal crash test
Abstract Nowadays, safety is a competitive advantage for automotive products and therefore receives considerable attention by automotive research centers. In this paper, a frontal crash test of sedan product of an under development platform is simulated and occupant head injuries are investigated based on ECE R94 regulation. First, an initial evaluation of t

5. Development of a Heavy Containment Level Bridge Rail for Istanbul
Abstract The international highways within the city limits of Istanbul are used to transit more than 15 million trucks and other heavy good vehicles per year. According to the statistics, the number of single truck run of the road accidents is in the rise. Recent accidents on bridges showed that currently used bridge rails specified by Istanbul Metropolitan

6. Numerical Analysis of an Intercity Bus Structure: A Simple Unifilar Model Proposal to Assess Frontal and Semifrontal Crash Scenarios
Abstract To improve the safety of the intercity bus structure against impact scenarios and to reduce the injuries and death in traffic accidents it is crucial in a country with continental dimensions like Brazil, where the road transport matrix is fundamental in the traffic of people and goods. In this context in the present article, a numerical model of an

7. Studying energy absorption in tapered thick walled tubes
In many engineering structures different energy absorption systems may be used to improve crashworthiness capability of the system and to control damages that may occur in a system during an accident. Therefore, extensive research has been done on the energy-absorbing cells. In this paper, energy absorption in tapered thick walled tubes has been investigated

8. Estudo sobre o uso do aço bifásico como matéria-prima em componentes estampados de carrocerias veiculares
Neste trabalho foi analisado um aço conhecido comercialmente por dual phase, compreendendo a obtenção deste tipo de aço, suas propriedades mecânicas, a relação entre sua microestrutura e seu desempenho e um comparativo com um aço microligado. Comparados aos aços convencionais, os aços bifásicos, em virtude do melhor desempenho em serviço, podem p

9. Disponibilidade de bebidas alcoólicas e beber e dirigir
Alcohol abuse and traffic crashes (TC) are considered public health problems and every year they are associated with 2.5 and 1.2 million of deaths worldwide, respectively. Alcohol outlet (AO) density has been associated with Driving Under Influence (DUI), which is a well known risk factor for TC. However, the association is controversial in international lit

12. A generalized model for distributed comparison-based system-level diagnosis
This work introduces a new system-level diagnosis model and an algorithm based on this model: Hi-Comp (Hierarchical Comparison-based Adaptive Distributed System-Level Diagnosis algorithm). This algorithm allows the diagnosis of systems that can be represented by a complete graph. Hi-Comp is the first diagnosis algorithm that is, at the same time, hierarchica
