Parameter studies on impact in a lap joint
TL;DR: In this article, a beam impacting four springs with gaps is modeled to represent a loose lap joint, and six influential parameters are studied: damping ratio, contact stiffness, intermediate contact position, gap, excitation amplitude and beam height.

Intracytoplasmic sperm injection
TL;DR: In this paper, the authors describe a method for intra-cytoplasmic sperm injection, comprising the steps of: holding an oocyte (1101) at a distal end of a suction holder (1104), the suction holding comprising a lumen (1207), passing an injection needle (1105) into the oocyte(1101), along the lumen(1207) of the SUction holder(1104) and injecting a single sperm into the Oocyte, and then withdrawing the injection needle(1105).

Review of the dynamic behaviour of sports balls during normal and oblique impacts
Muhammad Adli Haron,Azrol Jailani,Nik Ahmad Faris Nik Abdullah,Rafis Suizwan Ismail,Shayfull Zamree Abd Rahim,Mohd Fathullah Ghazali +5 more
TL;DR: A review of impact experiment to study the dynamic behaviour of sports ball during oblique and normal impacts is presented in this paper. But the experimental results are analyzed and compared with the theories, in order to understand the dynamics behaviours based on the phenomenological occurrence.

A treatise on the analytical dynamics of particles and rigid bodies
TL;DR: In this article, a comprehensive account of analytical dynamics is given, starting from first principles with kinematics before moving to equations of motion and specific and explicit methods for solving them, with chapters devoted to particle dyanmics, rigid bodies, vibration and dissipative systems.

Coefficient of Restitution Interpreted as Damping in Vibroimpact
K. H. Hunt,F. R. E. Crossley +1 more
TL;DR: In this paper, the Kelvin-Voigt model is shown to be logically untenable, for it indicates that the bodies must exert tension on one another just before separating, and it denotes that the damping energy loss is proportional to the square of the impacting velocity, instead of to its cube.
