In a science fiction movie, when a spaceship explodes the vibrations from the shock wave destroy a nearby spaceship. if you were the science consultant for the movie what would your advice be for the producer?

As the other answers correctly point out, space is a vacuum. Shockwaves – and sound – need a medium to propagate through – like water or air. So there is no way for sound or shockwaves to spread in space. (Remember the tag line for the original Alien movie – “In space, no one can hear you scream.”)

That said, there are reasons why the explosion of one space ship might damage or blow up a nearby space ship – particularly debris from the first ship smashing into the second, but also perhaps radiant energy of some kind doing sufficient damage.

However, science fiction movies routinely ignore physics. Consider Star Wars – not only do the TIE fighers roar as they fly around, but all the fighters move in ways that you could never move in space, that mimic the way fighter aircraft move in atmosphere. And you hear explosions. And see energy beams moving through space. And the space ships can fly faster than light, etc., etc.

Movies do this for a few reasons. If you showed space craft flying accurately – the way they would have to in the real world – it would be a bit boring and would also look unreal to audiences, who are used to seeing unreal flying space craft, and planes in atmosphere. It would make it harder to tell the stories they want to tell if space ships couldn’t fly faster than light. Battles would look boring if you couldn’t hear the explosions and see the energy weapons. It’s more fun the way they do it.

So I think it is a judgment call what you do in a given movie – if you want to go with realism or space opera.

Mechanical Vibration and Shock, Sinusoidal Vibration $221.68 Mechanical Vibration and Shock Analysis, Second Edition Volume 1: Sinusoidal Vibration The relative and absolute response of a mechanical system with a single degree of freedom is considered for arbitrary excitation, and its transfer function defined in various forms. The characteristics of sinusoidal vibration are examined in the context both of the real world and of laboratory tests, and for both transient and steady state response of the single-degree-of-freedom system. Viscous damping and then nonlinear damping are considered. The various types of swept sine perturbations and their properties are described and, for the one-degree-of-freedom system, the consequence of an inappropriate choice of sweep rate are considered. From the latter, rules governing the choice of suitable sweep rates are developed. The Mechanical Vibration and Shock Analysis five-volume series has been written with both the professional engineer and the academic in mind. Christian Lalanne explores every aspect of vibration and shock, two fundamental and extremely significant areas of mechanical engineering, from both a theoretical and practical point of view. The five volumes cover all the necessary issues in this area of mechanical engineering. The theoretical analyses are placed in the context of both the real world and the laboratory, which is essential for the development of specifications.

Mechanical Vibration and Shock, Random Vibration $206.15 Mechanical Vibration and Shock Analysis, Second Edition Volume 3: Random Vibration The vast majority of vibrations encountered in a real-world environment are random in nature. Such vibrations are intrinsically complicated, but this volume describes a process enabling the simplification of the analysis required, and the analysis of the signal in the frequency domain. Power spectrum density is also defined, with the requisite precautions to be taken in its calculation described together with the processes (windowing, overlapping) necessary for improved results. A further complementary method, the analysis of statistical properties of the time signal, is described. This enables the distribution law of the maxima of a random Gaussian signal to be determined and simplifies calculation of fatigue damage to be made by the avoidance of the direct counting of peaks.

Mechanical Vibration and Shock, Mechanical Shock $204.46 Mechanical Vibration and Shock Analysis, Second Edition Volume 2: Mechanical Shock This volume considers the shock response spectrum, its various definitions, its properties, and the assumptions involved in its calculation. In developing the practical application of these concepts, the shock shapes or profiles most often used in test facilities are presented, together with their characteristics and indications of how to establish test configurations comparable with those of the real-world, measured environment. Following this analysis there is a case study of how to meet these specifications using standard laboratory equipment, shock machines, electrodynamic exciters driven by a time signal or a response spectrum. Discussion of the limitations, advantages and disadvantages of each method is presented.

Mechanical Vibration and Shock $237 Mechanical Vibration and Shock Analysis, Second Edition Volume 5: Specification Development This volume focuses on specification development in accordance with the principle of tailoring. Extreme response and the fatigue damage spectra are defined for each type of stress (sinusoidal vibration, swept sine, shock, random vibration, etc.). The process for establishing a specification from the life cycle profile of the equipment which will be subject to these types of stresses is then detailed. The analysis takes account of the uncertainty factor, designed to cover uncertainties related to the real-world environment and mechanical strength, and the test factor, which takes account of the number of tests performed to demonstrate the resistance of the equipment.

Mechanical Vibration and Shock, Fatigue Damage $222.06 Mechanical Vibration and Shock Analysis, Second Edition Volume 4: Fatigue Damage Fatigue damage in a system with one degree of freedom is one of the two criteria applied when comparing the severity of vibratory environments. The same criterion is also employed for a specification representing the effects produced by the set of vibrations imposed in a real-world environment. In this volume, which is devoted to the calculation of fatigue damage, the author explores the various hypotheses and models used to describe the behavior of material suffering fatigue and the laws of fatigue accumulation. He also considers the methods of counting response peaks, which are used to establish a histogram when it is impossible to use the probability density of the peaks obtained with a Gaussian signal. The expressions for mean damage and its standard deviation are established and other hypotheses are tested.
