This bachelor’s thesis, which has been commissioned by HAMK Tech, a research unit within Häme University of Applied Sciences, is a part of a larger research project focused on high-strength steel applications and welded connections. The primary objective of this thesis is to understand the main features of Abaqus CAE and provide valid instructions on how to use software for the simulation of the butt-welded tensile test specimen S700 with a thickness of 4 mm. This thesis builds upon previous research and tensile experiments executed in HAMK Tech laboratories.
The goals of this thesis are to describe the steps of modeling with Abaqus, and the calculations required using the test results received from HAMK Tech. The thesis includes various example models and the description of the modeling process. The modeling process includes several key tasks such as defining geometry, specifying key parameters, and defining the valid input data for material properties. Previous bachelor’s theses serve as valuable sources, contributing to the continuity of the research.
Significant advancements have been made in this thesis, particularly in the areas of reducing the simulation time and defining the input data. The created models depict the realistic failure mechanism of the specimen and provide valid output data as force-displacement and stress-strain curves.
