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.
In this project, you will analyse the head impact on the car hood in LS-DYNA software,
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 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.
In this project, you will set up a case study for head impact simulation in LS-DYNA. Basically, you are supposed to replicate a scenario where the headform will impact the car hood. The headform and hood geometry are provided separately. These geometries should be organised by multiple include keywords. The headform is transformed to make an impact angle between 35-75 degrees and given fixed velocity. Proper material models and contact definitions are chosen for the given geometries and relevant post-processing results are requested through LS-PrePost. The stress-strain plots, system energy and other global statistics are analysed through the results. Head injury criteria/coefficient (HIC) is also calculated through postprocessing tool LS-PrePost. Based on the HIC value and other results the severity of the impact is interpreted.

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.
