A systematic treatment of current crashworthiness practice in the automotive, railroad and aircraft industries. Structural, exterior and interior design, occupant biomechanics, seat and restraint systems are dealt with, taking account of statistical data, current regulations and state-of-the-art design tool capabilities. Occupant kinematics and biomechanics are reviewed, leading to a basic understanding of human tolerance to impact and of the use of anthropometric test dummies and mathematical modelling techniques. Different types of restraining systems are described in terms of impact biomechanics. The material and structural behaviour of vehicle components is discussed in relation to crash testing. A variety of commonly used techniques for simulating occupants and structures are presented, in particular the use of multibody dynamics, finite element methods and simplified macro-elements, in the context of design tools of increasing complexity, which can be used to model both vehicles and occupants. Audience: An excellent reference for researchers, engineers, students and all other professionals involved in crashworthiness work.

Governed by strict regulations and the intricate balance of complex interactions among variables, the application of mechanics to vehicle crashworthiness is not a simple task. It demands a solid understanding of the fundamentals, careful analysis, and practical knowledge of the tools and techniques of that analysis. Vehicle Crash Mechanics s

Side-impact collisions can cause grave injuries. Often called "T-bone" or "broadside" collisions, side impact accidents occur when the side of a vehicle is impacted. The side of the car is the second most frequent impact location in fatal crashes, and also nowadays side impact crash fatalities have increased while the number of deaths related to front impact crashes has declined. This was due to the location of the impact is very close to the passengers and they will immediately receive the impact. The purpose of this dissertation is to analyze and simulate the side impact beam with the impacted crash load. The analysis was done to the side impact beam using three different type of material which are steel, stainless steel and aluminum in order to compare which material have the best performance to absorb the impact. The project started with the 3D CAD modeling of side impact beam that was referred with Perodua Kancil side impact beam, then being analyzed by using Ansys software. In FEA, there are some stages that were applied which are the material selection stage and type of side impact crash method. From the simulation data the best material, Aluminum alloys (Aluminum 6061-T6) was chosen and then few improvement was suggested with the existing design of side impact beam. Then two new design were designed and being analyzed. The final result shows that new design 2 has better result in terms of weight reduction with same performance. As conclusions, the best material for side impact beam to replace structural steel is aluminum alloys (aluminum 6061-T6) because it has the lowest value of Von Mises Stress but the highest deformation which show that it can absorb more impact energy compared to the other two materials. New design 2 was selected as best design to replace the existing design although the new designs has less difference in the analysis value which indicates that there is no huge impact but Design 2 has the lowest weight than other design. Its weight can be reduced up to 34% than the original weight.
