Back to original languageAbout Zahra
R&D Engineer specializing in materials mechanics and numerical simulation (ANSYS, Abaqus, FORGE, Quickcast), I support companies in the design, optimization, and validation of metallic and composite structures. I develop reliable numerical models, analyze mechanical behavior in static, dynamic, fatigue, and fracture, and provide tailored solutions to improve performance and reduce costs. Specifically, I work on projects involving the design, modeling, and simulation of forming processes: sheet metal bending and stamping, as well as numerical simulation of the casting process using Quickcast software, to analyze the behavior of liquid metal during filling and solidification. Following this study, a surface treatment is considered to improve mechanical properties and corrosion resistance.
My last experience at Capgemini Engineering involved dimensioning high-pressure hydrogen storage tanks for automotive applications, where I created custom calculation tools using (Excel, Python) and performed numerical simulations on ANSYS.
My goal: transform your ideas into concrete, robust, and innovative solutions.
Bring your projects to life with reliable, innovative, and competitive engineering solutions!
