Waqar A.

I help solve real-world mechanical and tribological problems using validated Finite Element Analysis (FEA), buckling & non-linear analysis, and Design Failure Mode and Effects Analysis (DFMEA). From early concept to production, my focus is on robust designs that survive in service, not just look good in a report. 🎓 Background PhD in Mechanical Engineering – Politecnico di Torino, Italy 20+ years of professional experience in design, analysis, testing and troubleshooting Experience with industrial projects across sectors such as marine, energy, process equipment, automotive, and machinery 🖥️ Software & Tools ANSYS Workbench & APDL ABAQUS SOLIDWORKS MATLAB LabVIEW Python 📊 Engineering Design, FEA & Buckling I provide end-to-end analysis support, including: Linear & non-linear static structural analysis Buckling and non-linear buckling (geometric & material non-linearity) Snap-fit and clip design (plastic and metal) including assembly forces, retention forces, and fatigue/safety assessment Thermal & thermo-mechanical analysis Seismic, modal, and frequency response analysis Fatigue life estimation and durability assessment Mesh convergence / grid independence and model validation Verification of FEA results with hand calculations Structural optimization (shape & topology optimization) 🏭 Industrial Applications (Examples) I work on practical, field-driven problems, for example: Buckling-induced delamination of coatings on ship hulls Analysis of coatings adhesively bonded to the ship’s main structure Cohesive zone modelling (CZM) and FEA to study buckling-induced delamination Objective: minimize coating failure and reduce corrosion risk and maintenance costs Pressure vessels and process equipment ASME BPVC VIII Div. 2 assessments Local stresses, nozzles, supports and attachments Buckling checks of shells, heads and stiffeners Sheet metal, thermoforming & hydroforming Springback prediction and compensation Formability and thinning assessment Welded structures and stiffened panels Snap-fits, housings & enclosures Design and optimization of snap connections Assembly/disassembly force assessment Evaluation of stress concentrations and long-term reliability Lightweight & special structures Beams, columns, supports, steel and aluminum frameworks Inflatable and flexible structures Aero and other safety-critical structures 🧪 Root Cause Analysis & Condition Monitoring Root cause analysis of failures (mechanical, thermal, tribological) Vibration and condition monitoring Lubricant analysis and interpretation for rotating machinery ⚙️ Tribology & Contact Mechanics Contact mechanics for sliding, rolling and mixed contacts Hydrodynamic and elasto-hydrodynamic lubrication Wear, fretting and surface damage mechanisms Surface characterization and Stribeck curve estimation Bearings, couplings, gears and other rotating components 📊 Research & Data Analysis Tribology and materials interface problems Design of Experiments (DoE) Statistical analysis and interpretation of test/field data 🗣️ How I Work I do not treat FEA as a black box. If the physics is wrong, the most beautiful contour plots are meaningless. Every model is built around realistic loads, boundary conditions, materials, and failure criteria. I explain assumptions, limitations and results in clear language so your team can make confident decisions. If I can’t explain it simply, I don’t understand it fully – and I hold myself to that standard. ❌ Strict NO to any academic / student work 👍 Big YES to long-term collaborations with industrial clients If you’re facing a non-obvious failure, buckling issue, snap-fit problem, or coating/tribology challenge, share a brief description and any available data, and we can discuss a structured, physics-based path to a solution.
