“…So accuracy is needed in the manufacture of mesh and for evaluating its quality. [26].In the process of this research meshing using Curvature based mesh as shown in the picture. Curvature based mesh divides the parts into triangular parts by analyzing the assembled parts according to the shape of the complex parts.…”

The Tensile Test Method on PLA material for product printing using a 3D printer will recommend the dove tail design as an interlocking part. The result of the design of the dove tail type as an interlocking join part is tested for the most optimal tensile strength. In this paper, consideration for the dove tail design used in material testing and will be printed using a 3D printer is in terms of technical ease of printing and technical testing of its physical form so that it can be gripped using a tensile test tool such as the Universal Tensile Machine (UTM). The dove tail design is designed with a scale representative size that meets the requirements of the standard clamp size of the test tool. Tensile force testing simulation using SolidWorks software will be used as a pre-tensile test analysis before being implemented by UTM. The results obtained are the deformation that is occurring, such as the PLA material having a higher deflection of 7,567 mm and the ABS material having a deflection of 1,897 mm. The strain on interlocking is 0.1081 for ABS material and 0.3988 for PLA material.

“…Many different works are reported in the literature about simulation of the laser welding process, with the objective to estimate the residual (and (or) transient) stress level in the final assembly. Most of the time, the corresponding works are based on a macroscale approach, by integrating a 3D mesh composed of elements with dimensions of about 100 μm or much more [1][2][3][4]. With this type of resolution, 3D transient simulations are possible, so that the corresponding models are able to predict the stress state vs. time during the welding process.…”

This work aims to study the influence of the shape of the weldseam on residual stresses in a laser welded assembly. The applied model directly uses micrographs of the weld cross‐section as mesh: for this, an in‐house tool was developed that makes it possible to convert micrographs into an APDL (Ansys Parametric Design Language) script command file readable by ANSYS. Application of a distinct reference temperature for the weld bead elements makes it possible to consider its shrinkage during cooling from the solidus temperature. Residual stresses related to thermal deformations can then be calculated. Welding of 304L stainless steel is considered as reference case.

“…This modern method of designing allows to efficiently fulfill the majority of time-consuming and currently expensive stages which together form the process of the creation of a new product [4][5][6][7][8][9][10]. It may be used both in relation to the whole construction, its subgroups, or individual components [11][12][13]. Fig.…”

This article presents the procedure of designing and testing the virtual prototype of the one-track vehicle using the Autodesk Inventor Professional software. A multi-stage process of preparing the virtual prototype and the results of selected simulation tests were presented. During the first stage of work, a digital geometric model of the vehicle was created. The second stage includes placing the model in the dynamic simulation environment and defining the testing conditions corresponding to the actual vehicle operation conditions. The next phase relates to the realization of virtual model tests in the Autodesk Inventor dynamic simulation environment. The model was subjected to tests using the multibody systems method (MBS) to determine the forces and displacements in selected structural nodes of the vehicle, in motion on uneven ground conditions. The obtained simulation results in the form of force values over time and displacements were analyzed and conclusions were formulated. The test results can be used to conduct a more detailed endurance analysis of individual construction elements, model optimization and impact on the driver’s body. It was stated that the used method allows for a more efficient process of creating a new product and more efficient evaluation of the impact of the conditions in which it will be used.
