Design methods and rule requirements have to be benchmarked with experimental or service history data. The Goal Based Standards (GBS) approach by IMO, see e.g., IMO Res. 296(87), 454(100) or MSC.1/Circ.1394, require benchmarking of standards by measuring the perfor mance of methodologies, assessments, criteria and requirements by using...

Owing to their low tensile failure strain, concrete is a difficult material to test under dynamic tensile loading. Indeed, conventional testing apparatuses such as high-speed hydraulic presses or Split Hopkinson Bar facilities rely on a mechanical balance of the specimen implying a short round-trip time in the specimen in comparison with the...

In this study, an experimental configuration that reveals the dynamic response of porous concretes in a drop weight impact test was introduced. Through the measurement of particle velocity at the interface, between the impactor and the concrete target, the dynamic response was obtained in an easily applicable way. Laser Doppler velocimetry (LDV)...

The issue of the European Directive 96/27/EC: “Protection of Occupants of Motor Vehicles in the Event of a Side Impact” in 1998 marked an importantstep in improving vehicle safety in Europe, but also confronted car and restraint manufacturers with the difficulties of having to comply with different standards in the world. Subsequently,...

At TNO multi-directional mathematical human body models have been developed. The objective of this study was to simulate the rigid seat and standard seat JARI rear-impact sled tests using the MADYMO 50th percentile male model. The head and neck response of this human model and the volunteers were compared. From the simulation results of the JARI...

In 1996, the European Community released new regulations relating to frontal impact vehicle crash. One of the tests, the European offset crash, consists of crashing the car on a deformable barrier at 56 km/h with 40% of the car impacting on the barrier. The regulations require the dummy injury parameters such as the HIC, chest deflection, chest...

A human body model representing a mid size male has been presented at the 1998 STAPP conference. A combination of modeling techniques was applied using rigid bodies for most segments, but describing the thorax as a deformable structure. In this paper, this modeling strategy was employed to also develop a model representing a small female. The...

The European Enhanced Vehicle-safety Committee (EEVC/WG10 and WG17) proposed three component subsystem tests for cars to assess pedestrian protection. The objective of this study is to develop computer simulation models of the EEVC pedestrian subsystem tests. These models are available to develop a car confirming the pedestrian subsystem test...

Given the serious consequences of neck injuries resulting from rear-end collisions, this collision type has gained much attention lately. The low g loading levels and diffuse injuries require a crash dummy with an improved response compared to the available crash dummies. In the EC sponsored 'Whiplash' program several sled tests with human...

Prediction and assessment of seated postures are essential for ergonomic vehicle design whereas dynamic seat interactions are essential for impact conditions. This paper presents seat models and human models for both applications. An interface has been developed to convert RAMSIS human models and postures to MADYMO. Static seat interaction...

The first objective of this study was to determine if the cumulative effects of impact or smoothly arising compression would damage the matrix of articular cartilage. Canine cartilage explants were subjected to repeated impacts or to smoothly arising compressions of as much as 20 MPa at 0.3 Hz for as long as 120 minutes. An increase in the water...

Both RAMSIS and MADYMO are widely applied for computer aided vehicle design. Both programs are used to simulate occupant-vehicle interactions where RAMSIS focuses on ergonomics in normal driving conditions and MADYMO focuses on passive safety in impact conditions. This paper describes simulations of human seat interactions using RAMSIS and...

For the experimental characterization of behind-armour debris so-called metallic witness packs can be used. A metallic witness pack consists of an array of metallic plates interspaced by polystyrene foam sheets. To quantify the fragment mass and velocity from the corresponding hole area and position in the individual witness plates, perforation...

Mathematical modelling is widely used for crash-safety research and design. However, most occupant models used in crash simulations are based on crash dummies and thereby inherit their apparent limitations. Several models simulating parts of the real human body have been published, but only few describe the entire human body and these models...

Neck injuries resulting from rear-end collisions rank among the top car safety problems and have serious implications for society. Many rear impact sled experiments with volunteers and PMHSs have been performed in the past. However, in most of these studies, T1 kinematics were not obtained so that the kinematic behavior of the neck could not be...

This paper will provide an overview of the research work of the European Enhanced Vehicle-safety Committee (EEVC) in the field of crash compatibility between passenger cars. Since July 1997 the EC Commission is partly funding the research work of EEVC. The running period of this project will be two years. The progress of five working packages of...

Side-impact safety of passenger cars is assessed in Europe in a full-scale test using a moving barrier. The front of this barrier is deformable and represents the stiffness of an 'average' car. The EU Directive 96/27/EC on side impact protection has adopted the EEVC Side Impact Test Procedure, including the original performance specification for...

The EEVC Side Impact Test Procedure includes the measurement of head impact with the EUROSID dummy. It was recognized that this would evaluate only a limited range of the potential head contact locations within the vehicle. EEVC commenced a study of accident analysis and the evaluation of potential head impact subsystems tests. Three alternative...
