The mechanics of strain-induced crystallization in poly(ethylene terephthalate)
… PET exhibits the capability of undergoing strain-induced crystallization during processing, the result of which is increased stiffness and hardness as well as better dimensional stability. An experimental study of the strain rate, strain state, and temperature dependencies of the …

Ensaios de extrusão de barras entre matrizes de perfil sigmoidal
Preliminarily, simple and plane-strain compression tests were made with pure and commercial lead in order to determine their isotropy and work-hardening conditions. Strip-extrusion experiments were afterwards made with a sigmoidal die profile for the maximum reduction condition, and with a straight …

Effects of thermomechanical processing on microstructure and hardness profiles in AA6061 plates
Effects of rolling variables - strain (?), strain rate (?) and temperature (T) - on grain structure and hardness evolution in AA6061 plates were investigated by simulating the rolling process using plane strain compression (PSG). Particular emphasis was exerted on understanding the impact of the …

Investigating effects of interpass time during hot finish rolling on the evolution of texture in AA3104 Can Body Stock
… by simulating multi-pass, high-temperature plane strain compression tests on a Gleeble 3800. Two scenarios were simulated: Position A, with a longer inter-pass time between the first two passes and a shorter time before the third pass, and Position B, with reversed timings. Post-deformation, …

Temperature and rate dependent finite strain behavior of poly(ethylene terephthalate) and poly(ethylene terephthalate)-glycol above the glass transition temperature
… lies in the fact that it crystallizes at large strains during warm deformation processing. The imparted crystallinity increases its stiffness and strength, improves its dimensional stability, and increases its density. The crystallization process and the stress-strain behavior above the glass …

Hot formability and microstructural development of spray-deposited Al-Li alloy and composite.
… at elevated temperature by the test methods of plane strain compression (PSC) and torsion to provide stress-strain data for the formulation of constitutive relationships. Torsion testing also provided high temperature ductility data. Isothermal annealing of rolled samples was carried out at the …

Development and preliminary numerical investigations of a dislocation density-based finite-strain rate-dependent elastoplasticity constitutive model
… of a dislocation density-based finite-strain rate-dependent elastoplasticity constitutive model Finite-strain elastoplasticity constitutive models suitable for process-scale simulation are typically developed from empirical observations of phenomena of interest. Such models make use of …

Critical analysis of simulated thermomechanical processing of aluminium can body stock
Hot Plane Strain Compression (PSC) testing is a thermomechanical testing method used to simulate the deformation condition of industrial rolling. Thermomechanical processing (TMP) factors such as the amount of strain, strain rate and temperature all influence the microstructural evolution. The …

Determination of thermo-mechanical variables during plain strain compression testing
Plane strain compression (PSC) resting is a method used to simulate the deformation condition of industrial rolling, namely that of plane strain, and is used extensively to describe the influence of deformation variables, being strain, strain rate and temperature, on microstructural evolution. …

The relationship between texture and formability in sheet metals
… both Knoop hardness measurements and tensile and plane-strain compression tests. From the latter, formability and hardening parameters were obtained and compared with the predicted behaviour. The earing behaviour of some FCC and BCC sheet materials was predicted using a crystallogaphic model based …
