摘要:Abstract(#br)This paper reports on dynamic abuse tests on Li-ion cells, namely investigations on local indentation/intrusion into these cells. Two different types of cells have been investigated, pouch cells and elliptic cells. The elliptic cells were tested in two different stat...

摘要:Abstract(#br)Wrinkling is commonly observed when a rectangular plate is stretched with fully-clamped boundaries. Experimental results of a highly orthotropic polypropylene thin film show a counterintuitive phenomenon – wrinkles occur when stretched in the low-stiffness direc...

摘要:Abstract(#br)Deformation and failure of constrained cells and modules in the battery pack under transverse loading is one of the most common conditions in batteries subjected to mechanical impacts. A combined experimental, numerical and analytical approach was undertaken to revea...

摘要:Abstract(#br)When a long slender structure such as a wire, strut or rope is loaded under tension all the way to fracture, upon failure an elastic unloading wave propagates down the wire and reflects as a compressive wave from the distant clamp end. The compressive effect of ...

摘要:Abstract(#br)The present paper documents a comprehensive study on the ground impact of lithium-ion battery packs in electric vehicles. With the purpose of developing generic methodology, a hypothetic global finite element model is adopted. The force–displacement response of ...

摘要:Abstract(#br)Edge fracture has been a well-known challenge in the forming processes of Advanced High Strength Steels (AHSS). The difficulty of the problem mainly lies in the complex loading path of out-of-plane shearing followed by in-plane stretching. Existing Finite Element mod...

摘要:Abstract(#br)The present work deals with the concept of post-initiation softening applied to ductile crack initiation and propagation problems in thick structural components such as pre-cracked pipes and fracture specimens. The methodology includes a set of calibration steps to d...
