This book "Mechanics of Material Using Ansys Workench with Numerical Validation" aims to explore into the basics of structural analysis, focusing on a range of problems commonly encountered in Mechanics of Material subject.There are eleven fundamental Mechanics of Material problems; each explored using ANSYS Workbench, a powerful finite element analysis software tool. Through detailed analyses and simulations, readers will gain insights into the behavior of various structural problems and develop proficiency in utilizing ANSYS Workbench for real-world engineering applications.Moreover, for every highlighted problem addressed using ANSYS Workbench, there exists an analytical validation. This analytical validation serves as a benchmark for the accuracy and reliability of the computational results obtained through finite element analysis. By comparing computational findings with analytical solutions, readers can better grasp the distinctions of structural analysis and validate the efficacy of numerical techniques employed.
