In this project, you will learn how to validate the elasto-plastic material model with the given stress-strain data. You will learn the extraction and cleaning of the stress-strain data point from the given curve. Then you will study how to evaluate the hardening curve and give material parameters input to the LS-DYNA software. Finally, you will understand how to extract the stress-strain results from the simulation and compare it with the given data.
You will be performing a tensile test on a dogbone specimen to validate the elasto-plastic material model.
In this project, you will understand modeling of Material LAW-1- Elastic, LAW-2, LAW36 - Elastoplastic, and LAW-27-Brittle along with Johnson-Cook failure in Radioss. You will also understand XFEM formulation to understand the effect of cracking in the model.
In this project, you will analyse the head impact on the car hood. You will learn how to set-up the case study by giving the required geometry transformations, boundary conditions, material models, contact definitions. Stress, strain, head impact coefficient(HIC) values will be calculated and studied in post-processing.
Understand how to perform a tensile test to calculate the Mooney Rivlin and Ogden material parameters and compare it with the given stress-strain data. Learn how to use hyper-elastic material card and give particular inputs for simulation. Study and understand conversions from engineering stress-strain to true stress-strain and terms like stretch ratio and extension. Finally, understand curve fitting and compare the simulation and given stress-strain data.
In this project, you will simulate a tensile test on a given dogbone specimen to validate the elasto-plastic material model in LS-DYNA. The experimental stress-strain curve is used to extract the data points and further cleaned to avoid noisy data. You will evaluate the hardening curve from the extracted stress-strain curve and learn how to give that as an input in LS-DYNA. Understand conversions from engineering stress-strain curve to true stress-strain curve and effective stress/effective plastic strain. Understand how to give all boundary conditions for a tensile test and set up an error-free input file for the solver. Finally, run the simulation using this input file using the launch manager. Post-processing would be carried out in LS-PrePost and simulated results would be compared to validate the material model.

Engineering students who are fresh out of college often struggle to meet the expectations of their employers. More often than not, this stems from a gap between the skills they learned in school and those that are required to make them competitive in the workplace. Skill-Lync, an edtech startup based out of Chennai, aims to bridge this gap.
Chennai-headquartered online learning startup Skill-Lync has launched a Masters course in Electric Vehicle Design and Simulation. The company says the new course is the first such curriculum in India, that focuses on electric vehicles. The fee of the EV course is around Rs 275,000, with the option of a full time or part-time duration. The startup provides job leading courses for Mechanical, Electrical and Civil Engineering students in India and across the world. With colleges shut and students looking to make the most of the time that they are at home the startup has fast-tracked the development of this program and releasing it amid Covid-19.
Skill-Lync started out as a YouTube channel to share engineering tips. Today, it is an online training course that caters to mostly non-software engineering students, which make up around 60 percent of the total engineers that graduate every year.
In an attempt to ensure that there is no hiatus in student education during the ongoing lockdown, Govt of India’s All India Council of Technical Education - NEAT announced partnership with Chennai based Edtech startup Skill-Lync. The global startup Skill-Lync is first-of-its-kind engineering technical education platform that provides job leading courses for Mechanical, Electrical and Civil Engineering students in India and across the world.
