“…Post-processing finite element analysis (FEA) was the final step of the sequence for visualization of computing outcomes [29]. The main failure creation in this study selected Tresca or Maximum shear stress due to appropriate to analyze the plastic component design rather than Von-mises which is very sensitive to the hydrostatic stress component as mentioned by Mascarenhas [30].…”

The enormous use of plastic in any live sector will impact the waste plastic escalation. Unsorted and uncollected wasted plastic properly leads to the creation of mixed waste plastic in landfills. Therefore, mechanical recycling technology for processing mixed waste plastic into pasta phase has been developed. In this research, four sources of mixed waste plastic were implemented derived from household plastic bags (WPB), waste of plastic sack (WPS), waste of used carton beverage (WPAL) and waste plastic from drum pulper in pulp industry (WPI). Those materials were transformed into specimens through extrusion and compression molding, then tested for investigation the mechanical properties. A comparison of density, tensile strength, and compressive strength from each material was exposed comprehensively. Furthermore, finite element analysis (FEA) was employed to compute the reliability of recycle material properties in the pallet application under the racking condition test following ISO 8611 standard. Surprisingly, it was reported a potential performance with a maximum racking load until 700 kg for pallet product using all variants of mixed waste plastics. The maximum capacity was obtained based on consideration of the FEA result exhibited in tresca or maximum shear stress, total deformation, and factor of safety design.

“…Recent investigations have focused on the relative performance of tetrahedral and hexahedral elements [7,8], and point out the necessity of tetrahedral elements frequently requiring up to an order of magnitude more elements to achieve the same accuracy as hexahedral elements. In other words, the discretization of a workpiece with hexahedral elements is likely to require less nodes (or degrees of freedom) and, therefore, ensure faster CPU times.…”

This paper focuses from the fundamentals of finite element flow formulation to the main aspects of computer implementation and modelling of three-dimensional bulk forming processes. Fundamental research and development is based on a comprehensive analysis of a wide range of theoretical and computational subjects such as selection of elements, solution procedures, contact algorithms, and meshing and remeshing procedures. We also focus on elastic analysis of tooling and a simple algorithm is proposed for transferring the load across the die–workpiece contact interface.The overall study is supported by several specially designed, cold forming experimental parts that were manufactured under laboratory-controlled conditions. Comparisons between theoretical predictions and experimental results comprise a wide range of topics such as material flow, geometry, forming load and strain distribution.

“…Post-Processing techniques are often used in numerical simulations for a variety of reasons from visualisation purposes [4] to designing superconvergent approximations [5] through to becoming fundamental building blocks in constructing numerical schemes [6,12,13]. Another application of these operators is that they are a very useful component in the a posteriori analysis for approximations of partial differential equations (PDEs) [2,33].…”

In this work we examine a posteriori error control for post-processed approximations to elliptic boundary value problems. We introduce a class of post-processing operator that “tweaks” a wide variety of existing post-processing techniques to enable efficient and reliable a posteriori bounds to be proven. This ultimately results in optimal error control for all manner of reconstruction operators, including those that superconverge. We showcase our results by applying them to two classes of very popular reconstruction operators, the Smoothness-Increasing Accuracy-Conserving filter and superconvergent patch recovery. Extensive numerical tests are conducted that confirm our analytic findings.
