Aim- Use the given material data to build a hyper elastic material cards using Ls-Dyna. Build Mooney Rivlin and Ogden material card by finding their constants using d3hsp file. Perform uniaxial tensile test on Dogbone specimen with 100% strain (i.e. strain = 1) and compare the stress strain data in above cases. Theory-…

JOINT CREATION AND DEMONSTRATION IN LS-DYNA OBJECTIVES             In this challenge, we have to create joints Using the manual (*CONSTRAINED_JOINT keyword) to demonstrate spherical, revolute, cylindrical, and translational joints between two rigid bodies and two deformable…

MASS SCALING USING LS-DYNA   AIM:   To use mass scaling to reduce the runtime of a model and ensure the stability of mass scaling. To reduce the runtime required to run the analysis of the given model using mass scaling technique and stability has to be completely intact. To plot a histogram to compare the runtime…

LS DYNA – Phone_Drop_Analysis By Enos Leslie Mechanical Engineer 29th March 2021   Question: In this assignment, we provide you with a file having just nodes and elements of two parts, a simplified cellphone, and a plate mimicking ground. You need to create a complete simulation file from this to perform a drop test. *INITIAL_VELOCITY…

OBJECTIVE To carry out a tensile test on a created 10mmx10mmx10mm block and generate uniaxial tensile behaviour results from simulation using either the explicit or implicit solver. Additionally, the results are compared between ELFORM 1, 2, -1 & -2 of the created block using a plot of Engineering Stress vs Stretch…

LS DYNA – Ogden Material Modeling By Enos Leslie Mechanical Engineer 28th August 2021 OBJECTIVE: Model a tensile test in the implicit deck with material Ogden and compare with the graph below.  The Elform (1,-1, 2,-2) is varied and compared to the curve. TASK: An excel sheet with proper conversion and calculation…
