Abstract Microscale holes were punched at cryogenic conditions in polycaprolactone (PCL) membranes to create synthetic three-dimensional (3D) tissue scaffolds through multilayer stacking of two-dimensional (2D) porous membranes. Punching forces were experimentally measured, and finite element modeling of the punching process was validated by comparing punching force results. Holes of nominal diameter of 200 μm were punched in PCL films of two different thicknesses: 40 μm and 70 μm. Die clearances used for holes in 40 μm thick films were 15.0%, 30.0%, and 45.0%. Die clearances used for holes in 70 μm films were 8.6%, 17.1%, and 25.7%. All holes were punched while the PCL film was in thermal equilibrium with a bath of boiling liquid nitrogen. Punching forces were analyzed to study the effect of die clearance and film thickness. A 3D finite element simulation of the punching process was done using deform 3d software. Cryogenic material properties of PCL used in the simulation were determined experimentally. It was concluded that finite element simulation for the cryogenic micropunching process can be used to predict peak punching forces with reasonable accuracy, which is a key factor to be considered while designing the punching dies. The finite element simulations did not predict an optimal die clearance to minimize peak punching force. However, the measured peak punching forces for 70 μm thick film seem to favor the smallest die clearance to minimize peak punching force.

This paper describes how to use Deform-3D software to create a turning process model that can be used to simulate the turning on AISI 1025 carbon steel and Al6061 billets in industrial and automotive applications. The Deform-3D Software is used to build a 3D Finite Element turning model. Pre-processing, Simulation, and Post-processing are all modules that can be used to simulate. Tool and workpiece information, as well as appropriate necessary parameters, were taken into account in the software’s Pre Processing module. Simulation was performed at two different rotational speeds for two different materials using with and without titanium nitride coated tungsten carbide tool. After 1000 steps of simulation, results such as damage, effective strain, effective stress, total velocity, total displacement, and Temperature are reported from the Post Processing module. From results, comparative analysis will be carried out on performance characteristics at different rotational speeds. During the turning process, to accurately predict metal removal Deform 3D software is used for finite element simulation.

Based on the principle of disc slitting process, a 3D model of the disc slitting process for galvanized sheet was established by using DEFORM-3D software, and the deformation, fracture and material effective stress of galvanized sheet were analyzed. The surface morphology of numerical simulation is in good agreement with the actual result. The curve of shearing force was obtained and well matched with the change rule of slitting process. Compared with the theoretical calculation result, the simulation result is reliable and can provide a reference for the calculation of shearing force.

Finite element simulation of stable fatigue crack growth using critical crack tip opening displacement (CTOD) was done. In the preliminary finite element simulation without crack growth, the critical CTOD was determined by monitoring the ratio between the displacement increments at the nodes above the crack tip and behind the crack tip in the neighborhood of the crack tip. The critical CTOD was determined as the vertical displacement at the node on the crack surface just behind the crack tip at the maximum ratio. In the main finite element simulation with crack growth, the crack growth rate with respect to the effective stress intensity factor range considering crack closure yielded more consistent result. The exponents m in the Paris law were determined.

The effect of oscillation of internal pressure on the formability and shape accuracy of the products in a pulsating hydroforming process of T-shaped parts was examined by finite element simulation. The local thinning was prevented by oscillating the internal pressure. The filling ratio of the die cavity and the symmetrical degree of the filling was increased by the oscillation of pressure. The calculated deforming shape and the wall thickness are in good agreement with the experimental ones. It was found that pulsating hydroforming is useful in improving the formability and shape accuracy in the T-shape hydroforming operation.

This paper deals with experimental and finite element analysis of the stretch flanging process using AA- 5052 sheets of 0.5 mm thick. A parametrical study has been done through finite element simulation to inspect the influence of procedural parametrical properties on maximum thinning (%) within the stretch flanging process. The influence of preliminary flange length of sheet metal blank, punch die clearance, and width was examined on the maximum thinning (%). An explicit dynamic finite element method was utilized using the finite element commercial package ABAQUS. Strain measurement was done after conducting stretch flanging tests. A Mesh convergence examination was carried out to ascertain the maximum percentage accuracy in FEM model. It is found through finite element simulation that the width of sheet metal blanks has a greater impact on the maximum percentage of thinning as compared to preliminary flange length, and clearance of the punch dies.
