                                                         Assignment 10   1. Introduction In this assignment, a discussion will be made about two different formulations for…

                                                          Assignment 9 The objective of this assignment is to obtain the coordinates of several points of the stress-strain curve that are expressed in a figure. This data will be saved in a text file and then imported to LS-Dyna. A simulation will be carried in LS-Dyna and…

                                                                           Assignment 8 The objective of this assignemnt is to run a simulation in its original state (without changing paramenters that affect tha mass-scaling). After running the simulation, the parameters should be adjusted to minimize the computation time.…

                                                                            Assignment 7 This assignment is dedicated to the…

                                                                     Assignment 6 The objective of this assignment is to simulate 3 different load…

                                                          Assignment 4 - Crash box simulation With this project, the objective is to create a running simulation and extract…

                                                                  Assignment 3 - Drop Test Challenge   1. Material definition The first keyword to…

                                   Assignment 2 - Explicit and Implicit analysis 1. Explicit and Implicit methods The explicit and implicit methods are numerical algorythms that are used to approximate the exact solution of a function that depends of one or more variables. These metohds are useful in plenty of engineering…

                                           Assignment 1 - Consistency of units 1. Kg cm ms 1.1. MASS 1kg This measurement is directly written according to the mass units considered by this system: Mass 1 Kg = 1 Kg; Conversion factor (CF) = 1  1.2. LENGTH 1m Converting from m to cm, this measurement is given by: 1 m = 100…

1. The input file contains infprmation about the model itself. it stores that information in ASCII form. The engine file stores the information about the simulation controls (simulation time, animation printout frquency, etc...)   2. The Isolid 14 elements can be used when the user doesn\'t want hourglass effects…

                                                         Assignment 7 Unit system For reasons of simplicity, the unit system used is the same as in the provided files.  …

                                            Assignment 6 1. Unit system By opening the file neon_front_0000.rad (starter input deck), it was possible to check that the unit system was set to [Kg], [mm], [ms],…

                                                    Assignment 5 Case specification for the assignment: Case 1: Model as it is. Case 2: Inacti value set to 6 Case 3: Type 11 interface created.…

                                                  Assignment 4 In this assignment, 7 cases will be considered. Each case corresponds to one particular analysis setup. The setups for the analyses…

1. Updating the simulation time To do this, I went to the third line of the file FIRST_RUN_0001.rad and changed the time value to 55 ms, as shown in the image below. 2. Creating between 25 and 60 animation steps To create this amount of animation files, the time step has to be determined so that: To update this value in…

1. Velocity of sound in the steel rail The velocity of the sound in a solid is given bt the followin expression:                                                          Where…

                                                         Practice file 1. Geometry cleanup Using the \"Vizualization options icon\" displayed in the image below, it was possible…
