Clothing manufacturing uses non-linear finite element techniques to analyze the stresses on clothing such as; pants, shirts, sneakers, and lingerie. An interesting project by one of our participants was the analysis of a bra design. Excerpt from the web site OASYS - LS-DYNA Applications:In this particular case the consulting engineers, Ove Arup & Partners' Advanced Technology Group used dynamic non-linear finite element techniques to analyze the bras structural performance. A computational representation of the bra on a body was created by scanning the geometry of the model, Loen, who was featured in the program. The bra was then constructed using techniques usually associated with the modeling of airbags and seatbelts in cars. This enabled the non-linearity of the bra material, contact interaction with the body and large displacements to be represented. The performance of the bra was then analyzed by applying vertical accelerations to simulate a person jogging lightly or walking briskly. The analysis displayed fluctuating stresses in the bra cups and straps, varying with the walking pattern, and a higher constant stress around the base band where the bra was pulled tight onto the body |
