3D printing as a manufacturing system o ers new possibilities for designers. A key feature of it is the ability to print fully assembled mechanisms, while maintaining functionality. Due to the process of 3D printing, in order to create a mechanism some tolerance must be left between the parts, in order for them not to stick together. This tolerance changes from printer to printer. As such, a so...
In order to understand the mechanical behavior of granular deposit subjected to high-speed projectile impact, we perform both physical experiments and grain-scale numerical simulations. In the high-speed impact experiment, we adopted a new technology to observe the deceleration of projectile after penetrating into sand layer. The observed results together with simple one-dimensional model with ...
By now many experimental data on fully differential cross sections (FDCS) exist for single target ionization covering a broad range of different collision systems. At this stage it therefore seems reasonable to turn to somewhat more complex ionization processes and to fully exploit the opportunities provided by heavy projectiles, in order to advance our understanding of collision-induced few-pa...
in this paper, dynamical behavior of the delay mechanism of a special projectile controller is studied, using 3d finite element simulation. the controller considered here is among of high-acceleration mechanical controllers. due to high linear and angular accelerations of the projectile and also explosion risk, experimental investigation is very limited and almost impossible. so, numerical simu...
Two existing global medium-energy nucleon-nucleus phenomenological optical model potentials are described and compared with experiment and with each other. The rst of these employs a Dirac approach (second-order reduction) that is global in projectile energy and projectile isospin and applies to the target nucleus Pb. Here the standard S-V (isoscalar-scalar, isoscalar-vector) model has been ext...
