“…These are thought to be formed by the accumulation of many small cracks in a direction that is tangential to the inner surface. It appears that more than 10% tensile strain is sufficient to produce the occurrence of cracks [28]. This crack growths until it approaches the outer annulus, where a change in failure path occurs as the process approaches final failure [28].…”

“…It appears that more than 10% tensile strain is sufficient to produce the occurrence of cracks [28]. This crack growths until it approaches the outer annulus, where a change in failure path occurs as the process approaches final failure [28]. Along the shear plane, the final failure and shear lip occur depending on ductility, the mount of shear lip varies, strain rate and temperature [28].…”

In this study, we evaluated the cold drawing workability of two kinds of modified 9Cr-2W steel containing different contents of boron and nitrogen depending on the temperature and time of normalizing and tempering treatments. Using ring compression tests at room temperature, the effect of intermediate heat treatment condition on workability was investigated. It was found that the prior austenite grain size can be changed by the austenite transformation and that the grain size increases with increasing temperature during normalizing heat treatment. Alloy B and Alloy N showed different patterns after normalizing heat treatment. Alloy N had higher stress than Alloy B, and the reduction in alloy N increased while the reduction in alloy B decreased. Alloy B showed a larger number of initially formed cracks and a larger average crack length than Alloy N. Crack length and number increased proportionally in Alloy B as the stress increased. Alloy B had lower crack resistance than Alloy N due to boron segregation.

“…Young's modulus for PVC is 3.38 GPa [34], for copper it is 120 GPa [9]. These material properties were used to derive the spring constants k ¼ F=ΔL for the tensile (k t ) and radial stiffness (k r ) of the tubes [36] …”

a b s t r a c tComputer simulations are becoming increasingly important for the optimisation of various processes since they can significantly reduce the development time and costs. The discrete element method (DEM) offers a powerful tool for simulating the interactions of large numbers of particles. The method has proven its usefulness for many applications where granular and spherical particles are handled. Very recently DEM, was used to simulate the interactions of tubular particles. While the existing linear elastic models could describe the reversible bending and denting of these particles in a realistic way for small deformations, they are inadequate for describing the bending and compression behaviour at higher forces. In this region, buckling phenomena become important. Therefore, new phenomenological models, inspired by the collapse of steel tubes due to ovalisation of the cross section and the formation of plastic hinges, have been implemented for metal and synthetic plastic tubes. Using these models virtual, bendable tubes were created in the DEMeterþ þ software. The DEM parameters were calibrated for copper and PVC tubes based on combined bending and denting tests conducted using an Universal Testing System. The simulations were in good agreement with the measurements (R 2 4 0:91). This realistic DEM model of bending can, in future research, be used to simulate the processing of large numbers of tubular particles (e.g. the processing of crop stems).
