சி. எஸ். ஐ. ஆர். - கட்டமைப்பு பொறியியல் ஆராய்ச்சி நடுவம்

Objectives

• To develop a generalized concrete damage model for impact analysis of concrete structural components
• To propose expressions for computation of target penetration depth under impact load

Challenges

• Impulse load induces wave propagation in targets leading to scabbing and fragmentation
• Large number of wide ranging parameters involved in concrete damage model

Methodology

• Simplified analytical model by integrating moment balance equation and Newton’s second law of motion
• Nonlinear explicit transient dynamic analysis of concrete structural components for impact loading
• Calibrated the concrete damage model parameters using experimental results

Achievements

• Developed a generalized concrete damage model for impact analysis
• Separate expressions for plain and RC targets to compute penetration depth
• Simplified analytical model capable of predicting target penetration depth, residual velocity and target resistance
