Designing and manufacturing products — from lithium batteries to wearable devices — requires sophisticated engineering and scientific analyses to ensure safety and compliance.
Discuss your product development challenges and meet with Exponent's Thermal Sciences and Biomedical Engineering & Sciences experts as they present their latest product safety findings at the IEEE International Symposium on Product Compliance Engineering (ISPCE) 2023.
Attend Exponent's Product Safety Presentations at ISPCE 2023
"Thermal Runaway Energy Release as a Function of the State of Charge" | 11:00 a.m.
Francesco Colella, Ph.D., P.E., CFEI, Senior Managing Engineer, Thermal Sciences
Designing safe products powered by lithium batteries requires an understanding of how the battery pack will behave while undergoing thermal runaway. This presentation will discuss how fractional thermal runaway calorimetry is used to estimate the energy release from cells at different states of charge when undergoing a thermal runaway.
"Reduced-Order Modeling of Pennes' Bioheat Equation for Thermal Dose Analysis" | Part 1, 2:00 p.m.; Part 2, 3:00 p.m.
Artyom Kossolapov, Ph.D., Senior Associate, Thermal Sciences
In this study, reduced-order models based on proper orthogonal decomposition are developed for modeling transient heat transfer in partially-perfuse tissue in prolonged contact with a heat-generating wearable device. This methodology can provide fast, accurate temperature forecasts for arbitrary time-varying boundary conditions and heat sources.
"Computational Modeling of Sharp Edge Injury Hazards" | 4:00 p.m.
Scott Lovald, Ph.D., M.B.A., P.E., Senior Managing Engineer, Biomedical Engineering & Sciences
This study uses a finite element model of the human dermis to evaluate the laceration risk of generalized product edges. Based on comparison to experimental data, the results indicate there are consistent stress and strain criteria associated with an increase in laceration risk.
"One reason for the concern over the propagation of failures is that thermal runaway events can result in the venting of flammable gases, and these gases can generate a fire or an overpressure event if ignited in a confined area."
The 19th annual ISPCE event welcomes entrepreneurs and leaders, scientists and engineers, and more to the three-day symposium featuring a range of networking opportunities and presentations — from "product safety 101" to today's global regulatory challenges.
What Can We Help You Solve?
When fires, explosions, thermal, and flow-related accidents occur, timely response and expert analysis are critical. Exponent's thermal sciences consultants investigate root causes of failures, fires, and explosions for all types of accidents within residential, commercial, transportation, and industrial settings.
