TY - JOUR TI - ELASTIC-INELASTIC BEHAVIOR OF PET AND NYLON 66 MONOFILAMENTS UNDER LATERAL COMPRESSION AU - BATRA, SK AU - SYED, N T2 - JOURNAL OF POLYMER SCIENCE PART B-POLYMER PHYSICS AB - Abstract Results of experiments on short lengths of nylon 66 and PET monofilament specimens, subjected to lateral compressive force between two parallel platens, are described. In the experimental procedure the change in the compressed diameter and the area of contact were determined as a function of the applied force. From these data elastic moduli in lateral compression were estimated. The load–deformation behavior beyond the elastic range exhibited a yield‐like phenomenon. SEM examination of the deformed specimen suggest the possible modes of deformation in the post‐yield behavior. It is inferred that the yield occurs due to concentration of deformation along the maximum shear planes. The deformed specimens also show specific forms of fracture initiation and growth.

It allows the in situ observation of the deformation of the yam and fabric structures in attrition processes, such as the snagging of a knit fabric by a sharp needle point (or a hook) or the abrasion of a fabric by single or multiple macro-asperities. Some preliminary observations obtained with this device are discussed. DA - 1975/// PY - 1975/// DO - 10.1177/004051757504500405 VL - 45 IS - 4 SP - 303-307 SN - 0040-5175 ER -
