Particle-Based Medical Implant Simulations - Work with Lifespans, Ltd.

description

I worked as a simulation engineer for a Hong-Kong based startup called Lifespans. Lifespans develops particle-based orthopedic implant simulations that provide accurate force results faster and less expensive than in person tests and more accurate than FEA simulation testing. This aids in the implant protoyping design process.

documentation

Below are some examples of the results of our simulations. Leveraging knowledge of materials, their mechanical properties, and interactions between materials, I designed and ran particle-based simulations for orthopedic implants. This included developing instructions for the movement and interactions between parts, assigning appropriate material properties, and comparing simulation results with real-life test results to further optimize our simulator for behavioral accuracy. Our simulator was also used on novel implant geometries to understand where stress concentrations and part failure may occur and to understand load margins. My work generated the stress map and resulting force values while others on the team generated the final animations shown.
