Assignment 6

Bird Strike A bird strike is strictly defined as a collision between a bird and an aircraft which is in flight or on a take off or landing roll. The term is often expanded to cover other wildlife strikes - with bats or ground animals. Bird Strike is common and can be a significant threat to aircraft safety. For…

Objective: Using the manual (*CONSTRAINED_JOINT keyword) demonstrate spherical, revolute, cylindrical, and translational joints between two rigid bodies and two deformable bodies.  Procedure A joint is created using an even number of nodes, out of which every pair has the same position (XYZ coordinate). These nodes…

Objective To calculate the Mooney Rivlin and Ogden material constants and compare the both using stress-strain data from a Dogbone specimen tensile test with 100 percent strain. Procedue The given data is the engineering stress-strain are tabulated and the values are plotted as shown in the fig below   The given…

Aim: By using the diagram of true stress strain curve given data curve by using get data  graph digitizer.Crete a material 024 for an Dogbone specimen.Finially validate the mat card by performing the tensile test on Dogbone specimen and compare the results. Objective: Extract the data from the diagram  Clean…

Objective: To perform the mass scaling to reduce the runtime of a model and ensure the stability of mass scaling. The hard limit on mass scaling is 8% and stability should be completely intact.Mass is added by changing DT2MS as well as TSSFAC.Once the mass scaling objective is reached, a histogram should be plotted to…

Pedestrain Head Impact  Pedestrian protection CAE is a part of vehicle safety engineering from a crash perspective. In pedestrian protection, we look for imparting minimum injury to head, upper leg (thigh), and lower leg (including knee) in case of an accident with a human subject. These tests are usually done at…

Aim: 1.Create a block of 10mmx10mmx10mm dimension with 10 elements for each direction and use the material card attached (Ogden_Material.k) 2.Use appropriate boundary conditions to simulate tensile behavior for the model. 3.Compare the results for the simulation using ELFORM = 1, 2, -1, -2  4.Use a proper solver (Implicit/Explicit) …

Objective: The aim of the challenge is to study about spot weld  for the given assembly of the part and run a crash test using ls dyna. Also compare the results for spot weld made by beam elements and solid elements.And unit system followed by these assignment is gm mm ms. Procedure for Beam elements. 1. Keyword file…

Aim: In this Challenge we have to perform a stimulation of crash box it s is quit similar like car crash, but in these case instead of car we have taken an rectangular box which moves to an certain velocity and get crashed into a rigid wall Crush box is one of the components in automotive which absorb the crash energy.…

Objective: To perfom a drop test analysis on the given meshed model. by providing a appropriated velocity and boundary conditions using LS dyna software and conclude the result. If we accidental drop of mobile phone in daily life is probably the most common failure.Mobile phone is expected to continue functioning…
