Finite element analysis of RC beams using static experimental data to predict static and dynamic behaviors.

This study comprehensively compares dynamic and static forces in reinforced concrete (RC) beams, utilising experimental and finite element analysis (FEA) methodologies. Experimental tests involve monotonic two-point loading of 1 m x 150 mm x 150 mm RC beams using a universal testing machine (UTM). Deflection measurements are taken at three distinct locations (S1-S3) using various sensors, including force resisting sensor (FRS), flex sensor (FLS), MEMS accelerometer, and Piezoelectric sensors.

Force calibration for an endovascular robotic system with proximal force measurement.

Surgeons, while performing manual endovascular procedures with conventional surgical tools (catheters and guidewires), experience forces on the tool outside the patient's body that are proximal to the point of actuation. Currently, most of the robotic systems for endovascular procedures use active catheters to navigate vasculature and to measure the contact forces at the distal end (tool tip). These tools are more expensive than the conventional surgical tools used in endovascular procedures.

Design and Development of Surgeon Augmented Endovascular Robotic System.

Objective: Inadequate visual and force feedback while navigating surgical tools elevate the risk of endovascular procedures. It also poses occupational hazard due to repeated exposure to X-rays. A teleoperated robotic system that augments surgeon's actions is a solution.
