“…Generate optimized lattice and mixed solid -lattice structures, visualize simulation results in 3D, and export lattice designs in a .stl file format for 3D printing. View and interactively assign loads to load cases and import / export design loads in .csv file format with the new Load Cases Table. A recipe of the operation for a final optimal design is then presented to the manufacturing engineers thus saving them time and cost optimal design is then presented to the manufacturing engineers thus saving them time and cost [2], [5], [8].

“…[4]Sheet metal structures for instance are typically used to create automotive components that provide significant structural support under high loads, such as bumpers, seat frames and body in white parts. Particular focus is consequently placed in the optimisation of automotive components to produce designs that both perform well and are cost-effective [5]. Finite element analysis is widely used in Automotive parts such as rubber product design to choose the appropriate material models and determine the related material parameters So that a products can suffer from large deformation upon working conditions while behaving as a non-linearly elastic, isotropic and incompressible material.…”

In an optimization problem, different candidate solutions are compared with each other, and then the best or optimal solution is obtained which means that solution quality is fundamental. Topology optimization is used at the concept stage of design. It deals with the optimal distribution of material within the structure. Altair Inspire software is the industry's most powerful and easy-to-use Generative Design/Topology Optimization and rapid simulation solution for design engineers. In this paper Topology optimization is applied using Altair inspire to optimize the Sheet metal Angle bracket. Different results are conducted the better and final results are fulfilling the goal of the paper which is minimizing the mass of the sheet metal part by 65.9% part and Maximizing the stiffness with Better Results of Von- Miss Stress Analysis, Displacement, and comparison with different load cases. This can lead to reduced costs, development time, material consumption, and product less weight.

“…Optimisation methods in AM have been a theme for a profusion of Review Articles along the last decade. While some assess manufacturing technologies and how optimisation methods can be accounted for in the process [124][125][126][127][128], others analysed the suitability of TO approaches for given AM endeavours, such as construction in Buchanan and Gardner [129], aerospace structures in Plocher and Panesar [130] or the automotive industry in Sehmi et al [131]. Moreover, optimisation approaches impact the AM customised health-…”

Topology Optimisation is a broad concept deemed to encapsulate different processes for computationally determining structural materials optimal layouts. Among such techniques, Discrete Optimisation has a consistent record in Civil and Structural Engineering. In contrast, the Optimisation of Continua recently emerged as a critical asset for fostering the employment of Additive Manufacturing, as one can observe in several other industrial fields. With the purpose of filling the need for a systematic review both on the Topology Optimisation recent applications in structural steel design and on its emerging advances that can be brought from other industrial fields, this article critically analyses scientific publications from the year 2015 to 2020. Over six hundred documents, including Research, Review and Conference articles, added to Research Projects and Patents, attained from different sources were found significant after eligibility verifications and therefore, herein depicted. The discussion focused on Topology Optimisation recent approaches, methods, and fields of application and deepened the analysis of structural steel design and design for Additive Manufacturing. Significant findings can be found in summarising the state-of-the-art in profuse tables, identifying the recent developments and research trends, as well as discussing the path for disseminating Topology Optimisation in steel construction.

Concurrent topology optimization of multiple components sharing partial design domain based on distance regularized parameterized level set method

In this article, the distance regularized parameterized level set method (DRPLSM) is proposed, which introduces a specified energy functional into the level set equation as the distance regularization term. Geometric verification shows that the distance regularization scheme keeps the level set function near the structural boundary as an approximate signed distance function. Based on benchmark example of the cantilever beam, it is verified that the DRPLSM can avoid the re‐initialization of level set function in the optimization process and obtain smooth structural boundary. The DRPLSM is applied to multicomponent concurrent topology optimization with partially shared design domain for the first time. It makes the optimization results have smooth structural boundaries. The optimization objective of this algorithm is to minimize the structural compliance of all components. The sharing domain is divided into different design domains according to the strain energy of elements. The optimality of the proposed algorithm for partitioning the sharing domain is verified using the literature example with known optimal solutions. A symmetric structure example, a main and auxiliary optimization structure example and an example with design‐dependent boundary loads show that the proposed concurrent optimization algorithm has wide applicability.
