This paper investigates flexural behavior and analytical approach for predicting the load and deflection at critical performance points of reinforced concrete (RC) beams strengthened with prestressed carbon fiber-reinforced polymer (CFRP) sheets. A finite element model is developed to simulate the interaction between the RC beam and the CFRP sheets, capturing key aspects such as failure modes, ultimate load, and mechanical behavior across the three phases of failure.

This research aims to numerically simulate the performance of the tested PC utility poles using Applied Element Method (AEM) and Finite Element Method (FEM). The simulation results demonstrate that both AEM and FEM effectively reproduce the load-displacement relationship observed in the test. Additionally, this study discusses the material models employed in simulations, considering the limitations inherent in numerical modeling.

This thesis deals with the finite element simulation of spot welded joint in crash analysis. Spot welding is a very common joining process in the automotive industry. It is cost effective and it provides a very fast production rate of automotive body components. Despite this advantage, spot welds are very susceptible to various types of loading conditions. Therefore they are prone to failure, if not designed properly, during their service life time. Therefore it is very important to understand the behaviour of spot welds and their failure characteristics.

This study focuses on experimental testing and subsequent numerical analysis of impacted and pre-loaded composite coupons and bonded composite scarf joints under varying impact conditions. A methodology will be developed for the numerical modelling of preloaded impact tests to enable capture of critical failure modes and ultimate failure. The main aim is to validate a modelling strategy that will provide accurate failure characterisation of the tested joints using numerical analysis.

This thesis derives closed form equations to describe electromagnetic device characteristics for a toroid, solenoid and a case study induction machine. By considering stored magnetic field energy, this approach allows the relationship between electrical, magnetic and kinetic energy to be quantified and analyzed in ways that allows improved accuracy compared with conventional magnetic circuit modeling methods. This thesis also provides insights into how geometric parameters impact energy transfer and operational characteristics of electromagnetic devices.

A new electromechanical press for fuel pellet manufacturing was built last year in partnership between CEA-Marcoule and ChampalleAlcen. This press was developed to shape pellets in a hot cell via remote handling. It has been qualified to show its robustness and to optimize the compaction cycle, thus obtaining a better sintered pellet profile and limiting damage.
