কলঙ্কের মুক্ত শিকল
দ্রোহের কোন শব্দ নাই তাই বলে নিশ্চুপ থাকা ভাষা বা প্রতিউত্তর হতে পারেনা। ধর্ম ও মনুষ্যত্বের সীমারেখায় দাঁড়িয়ে বিশ্ববিবেক এবং ফিলিস্তিনের সংকটের এক আত্মিক প্রতিফলন।

Undergraduate Thesis (2024–2025)
Multi-Objective Optimization of Connecting Rods: A Coupled Thermal-Structural Approach
- Developed a comprehensive finite element simulation framework in ANSYS Workbench coupled with SolidWorks for heavy-duty IC engine connecting rods under combined peak thermal and mechanical combustion loading.
- Formulated and implemented a multi-objective optimization scheme using Sum of Squared Errors (SSE) minimization across 45 material configurations (Structural Steel AISI 4340, Aluminum 7075-T6, and Titanium Ti-6Al-4V).
- Quantified component mass, static factor of safety, fatigue safety factor, and material economy to achieve globally optimal strength-to-weight bimaterial combinations.
- Investigated Rule of Mixtures (ROM) homogenization models and resolved shear stress transfers across material interfaces.

Transition-Layer Design & Optimization of Functionally Graded Material (FGM) Connecting Rods
- Engineered a continuous 8.85 mm FGM transition interface joining an Aluminum alloy shank to Structural Steel bearing ends, eliminating sharp material discontinuities and mitigating delamination risk.
- Formulated and comparatively evaluated 5 spatial material gradation laws V₁(x): Linear, Exponential (β = 0.2, 0.5, 1.0, 1.5, 2.0), Sigmoid, Logarithmic, and Trigonometric.
- Tracked 10 distinct structural & fatigue metrics: equivalent von Mises stress, deformation, elastic strain, strain energy, static SF, fatigue life, fatigue damage, fatigue SF, and biaxiality.
- Executed localized stiffness matching and geometric fillet optimizations, achieving a 14.88% boost in factor of safety (5.29 vs. 4.61) over bimaterial joints.
