摘要

The IITDHBM IM50S finite element model, based on Indian Anthropometry is designed for explicit dynamic simulations within the LS-Dyna™ environment and serves as a pivotal tool for understanding human body responses under various loading conditions. This paper outlines the comprehensive development methodology of the model, which is divided into modular extremities. The paper addresses the development of individual body regions in detail, encompassing the head, neck, torso, hip, and upper and lower extremities. Material properties, geometric parameters, ligaments, and muscles were carefully considered for each body region. Sensors placed at different locations in the model enable the extraction of relevant data for injury prediction and severity assessment. The modularized IITDHBM IM50S allows users to simulate and analyze different body regions with varying levels of sophistication, enhancing flexibility and accuracy in simulations. Verification and validation of the model are crucial, with detailed validation outcomes against PMHS experiments forthcoming. Stability assessments under extreme loading, particularly blast loading scenarios, have been undertaken to ascertain the model’s response to such high-pressure waves. This paper presents a comprehensive overview of the development of the IITDHBM IM50S finite element model in extreme loading conditions, showcasing its potential to contribute significantly to injury prevention and mitigation strategies in crash and blast scenarios for the Indian population.
