Investigating the Strain and Degradation Parameters of Rapidly Discharging Lithium-ion Batteries using 3D Digital Image Correlation

Correlated Solutions recently assisted in an important research project in the College of Engineering and Computing at the University of South Carolina with members of Dr. Austin Downey’s research group who are investigating the degradation parameters of rapidly discharging Lithium-ion batteries in the ARTS lab (Adaptive Real-Time Systems). In some cases – especially in defense and aerospace applications – it is necessary to push battery performance to extreme limits. Dr. Downey’s team, working with support from the NSF and Airforce Research Laboratory are using a NHR 9200 Battery Test System to investigate the material characteristics of an 18650 2500mAh 20A battery as it rapidly discharges.

In this test, the focus is on Current Interrupt Devices (CID). CIDs play a critical role in ensuring safety in high-performance battery applications by interrupting current flow when it exceeds a predetermined safe limit. This prevents battery cells from overheating, which can lead to damage, fire, or even explosion. In high-performance batteries that are designed to deliver large amounts of current very quickly, this protection is essential to prevent catastrophic failure.

Analysis of Geometric Accuracy and Thickness Reduction in Multistage Incremental Sheet Forming using DIC

This paper describes a series of experiments in which truncated cone geometries were formed using two multistage methods and compared to the same geometry formed using the traditional single stage method. The geometric accuracy and thickness distributions, including 3D thickness distribution plots, of each are examined using digital image correlation (DIC).

DIC for Rail Neutral Temperature & Stress Measurements

The proposed method is based on measurements of nonuniform deformations of the rail under thermal loading, as observed in computer simulations and laboratory investigations. The implementation uses thermal imaging and three-dimensional stereo-digital image correlation technology to acquire full-field deformations.

Behavior of Metals During High-Speed Dynamic Compression

Studying the behavior of metals during a high-speed dynamic compression event has always been challenging due to the complex test set up and fast data capture rates required. Currently, very little literature is available regarding deformation behavior at strain rates of 10 to 500s-1. Utilizing high-speed cameras, the VIC-3D HS system can be used to quantify the surface displacements and strains in three dimensions over the entire field with great precision. Digital image correlation (DIC) has gained widespread popularity over recent years in such high-speed applications due to its high accuracy, flexibility and ease of use.

Adhesion Energy of Graphene on Nickel Substrates

In this study, for the first time, a novel full-field three dimensional (3D) blister test via stereo-digital image correlation (StereoDIC) was developed to characterize the interfacial interaction between as-grown graphene on nickel (Ni) and copper (Cu) substrates, respectively.

Printed Circuit Board (PCB) Measurement from Thermal Loading

Printed circuit boards (PCBs) have two primary functions: to provide electrical connections between terminals on the board, and to affix electronic components such as resistors, capacitors, and microchips via soldering. PCBs are used in many devices around the world on a day-to-day basis. Their small and lightweight design allows them to be found in nearly every electronic device, such as smart watches, phones & computers, and even digital cameras.

Strains Within a 300µm Diameter Ball Solder in BGA

The VIC-3D Stereo Microscope System enables local analysis within very small elements. One industry that benefits from this small-field imaging is microelectronics. Small electronics, like ball grid arrays (BGA) seen here, are too far small for traditional DIC to provide enough resolution to obtain local strain distribution within the actual ball solder.
