Joining Process

Investigation of the mechanical behaviour of multilayered metallic materials obtained during novel joining technique called Constrained Compression (CC) is presented. 316L stainless steel material was used in CC to achieve multi-layered structure. Microstructural study based on light microscopy was performed focused presumably on the joining areas of the deformed metallic laminate. The qualitative and quantitative assessment of the processing conditions, microstructure development and microhardness distributions showed the possibility of achievement good bonding quality. Experimental study was supported by numerical stress and strain analysis. It has been shown that determination of the optimum processing parameters allowed for improvement of the joining process, which in turn will enable to produce multilayered metallic materials on a larger scale.

Basic Parameters

This study focused on stress and strain analysis of the cutting force of a branch knife with a replaceable cutting edge. The replaceable edge forms part of the delimbing head, which is applied to the arms of a mechanical harvester working in forestry. Basic parameters of the knife and head of the harvester with the basic calculations necessary to determine the number of knives based on input parameters, such as wood diameter, woody plants, and determination of the cutting force acting on the cutting knife, were examined. Based on the cutting force and the design of the special cutting knife, a stress analysis and a finite element method (FEM) was performed. This study confirmed the correctness of the selected material to produce the delimbing knife, which was designed using a replaceable cutting edge. The output of the stress analysis is reported.

Stainless Steel Material

Stainless steels are used for the construction of numerous spent nuclear fuel or radioactive material containers that may be subjected to high strains and moderate strain rates during accidental drop events. Mechanical characteristics of these base materials and their welds under dynamic loads in the strain rate range of concern are not well documented. However, three previous papers [1, 2, 3] reported on impact testing and analysis results performed at the Idaho National Laboratory using 304/304L and 316/316L stainless steel base material specimens that began the investigation of these characteristics. The goal of the work presented herein is to add the results of additional tensile impact testing for dual-marked 304/304L and 316/316L stainless steel material specimens (hereafter referred to as 304L and 316L, respectively). Utilizing a drop-weight impact test machine and 1/4-inch to 1/2-inch thick dog-bone shaped test specimens, additional impact tests achieved target strain rates of 5, 10, and 22 per second at room temperature, 300, and 600 degrees Fahrenheit. Elevated true stress-strain curves for these materials at each designated strain rate and temperature are presented herein.

Abstract Additive Manufacturing (AM) particularly laser powder-bed fusion, is advancing rapidly in manufacturing industries. Selective laser melting (SLM) also known as 3D-printing has become one of the most recent developed and extensively used techniques for several manufacturing processes. However, processing parameters influence the defect formation mechanisms such as porosities, holes, cracks, incomplete fusion and molten pool configuration during the SLM process of metallic powders. Even though an extensive amount of work have been done in minimizing these defect formations by simply varying processing parameters such as laser power, deposition thickness and scanning speed, it is of great importance to study the heat transfer mechanisms in laser heating process and utilize the optimum process parameters in minimizing the residual stress and strain as well as improving the quality of a manufactured product. In this present work, the authors implement a numerical thermo-mechanical model approach to determine the residual stress and strain in 316L Stainless Steel built samples using a finite element method (FEM) software ANSYS® (Workbench version 19.0). We are able to predict the unsteady temperature distribution of temperature-dependent thermal properties, residual stress and strain as a result of the rapid melting and solidification of 316L Stainless Steel metallic powder with optimized processing parameters. From the simulation result, it is shown that the residual stress decreases with an increase in scanning speed, hatch distance and preheat temperature. However, an increase in melting temperature also increases the residual stress and strain in the simulated 3D built part.

Fea Analysis

The objective of this paper is to perform FEA analysis to establish a baseline analysis for the feasibility/optimization of the sidewalls for a simple wind box. A basic static finite element analysis (FEA) was run using Pro/Mechanica on the wind tank. The tank had corrugated walls, a flat bottom except for 3 sparse corrugations, and header that attaches to the top of all the tank walls around the perimeter of the tank. All components in the tank were constructed from 316L Stainless Steel material. Loads on the tank were then applied in the form of gravity (acting on all parts of the tank) and pressure (designated at 10 psi) acting on all the sidewalls and bottom of the tank. To make the analysis more efficient the model was idealized using shell elements, where applicable. The FEA analysis was completed to compare triangular, sinusoidal and trapezoidal sidewall designs for a simple wind box. The trapezoidal design was the best of the three designs, because it delivered the lowest stress and deformation levels. The sinusoidal and triangular corrugated walls provided a 6% reduction in needed material, but did not produce the same Factor of Safety as compared to the trapezoidal wall.

The Impact

Stainless steels are used for the construction of numerous spent nuclear fuel or radioactive material containers that may be subjected to high strains and moderate strain rates during accidental drop events. Mechanical characteristics of these base materials and their welds under dynamic loads in the strain rate range of concern are not well documented. However, a previous paper [1] reported on impact testing and analysis results performed at the Idaho National Laboratory using 304/304L and 316/316L stainless steel base material specimens at room and elevated temperatures. The goal of the work presented herein is to add recently completed impact tensile testing results at −20°F conditions for dual-marked 304/304L and 316/316L stainless steel material specimens (hereafter referred to as 304L and 316L, respectively). Recently completed welded material impact testing at −20°F, room, 300°F, and 600°F is also reported. Utilizing a drop-weight impact test machine and 1/4-inch to 1/2-inch thick dog-bone shaped test specimens, the impact tests achieved strain rates in the 4 to 40 per second range, depending upon the material temperature. Elevated true stress-strain curves for these materials reflecting varying strain rates and temperatures are presented herein.
