Background: Lower extremity injuries are frequently observed in car-to-pedestrian accidents and due to the bumper height of most cars, knee joint is one of the most damaged body parts in car-to-pedestrian collisions.Objective: The aim of this paper is first to provide an accurate Finite Element model of the knee joint and second to investigate lower limb impact biomechanics in car-to-pede...

INTRODUCTION Frontal and rear-end collision with low speed are common accident mechanisms in situations with dense city traffic. During a rear-end collision the car occupant of the struck vehicle is pushed forward by the seat-back. Due to its inertia the neck is forced to an extension-flexion movement commonly called ‘whiplash’. To improve car safety mainly anthropometric test dummies (ATD) e.g...

Car body deformation modeling plays a very important role in crash accident analyses, as well as in safe car body design. The determination of the energy absorbed by the deformation and the corresponding Energy Equivalent Speed can be of key importance, however their precise determination is a very difficult task. Although, using the results of crash tests, intelligent and soft methods offer an...

Objective: The current study is aimed at evaluating the effect of active muscle on the dynamics of the pre-impact bracing car occupant using numerical simulations. The objective of the study includes identifying the sensitivity of occupant injury metrics to the level of pre-impact bracing action. Problem Outline: Bracing or pre-impact muscle tensing, one of the key reflexive actions adopted fre...

background, aims, methods, results) max 200 words: Tilting trains reduce the perceived lateral acceleration for the passengers by tilting the car-body to improve the ride comfort. However, some susceptible passengers may experience nausea. To study the influence from either lateral accelerations and/or simultaneous roll motions, a simulator study was undertaken. About 40 subjects were taking pa...

Whiplash injuries are common following rear-end collisions. During such collisions, initially relaxed occupants exhibit brisk, stereotypical muscle responses consisting of postural and startle responses that may contribute to the injury. Using prestimulus inhibition, we sought to determine if the startle response elicited during a rear-end collision contributes to head stabilization or represen...

AIS 1 neck injuries has become the most common disabling injury in vehicle crashes. Research has shown that there are variations in rear impacts causing shortand long-term disability to the neck. Therefore impacts in where the duration of symptoms differ need to be separated in analyses. Crash severity is usually measured as change of velocity. The correlation between injury risk and impact sev...

The six-degree equations of flight in their classic form do not provide a proper physical perception due to a number of interferences. Nor do they render visible the important role of attack angles. In this study, attempts have been made to develop a complete set of 3D acceleration equations from the equations of normal and tangential acceleration αN=vωv, αt=v ̇. For this purpose, a coordinate s...

PURPOSE Pancreatic body/tail cancer often involves the celiac axis (CA) and it is regarded as an unresectable disease. To treat the disease, we employed distal pancreatectomy with en bloc celiac axis resection (DP-CAR) and reviewed our experiences. METHODS We performed DP-CAR for seven patients with pancreatic body/tail cancer involving the CA. The indications of DP-CAR initially included tum...
