Application of Finite Element Analysis for Fracture and Damage Mechanics

This book focuses on finite element analysis of various material models and their relevant fracture and damage models using ANSYS. It has three parts: Part I introduces the various material models, Part II highlights the finite element modeling of their relevant fracture parameters, and Part III deals with various material damage models.

Application of Finite Element Analysis for Fracture and Damage Mechanics focuses on the finite element analysis of various material models and their relevant fracture and damage models using this advanced software. The book consists of three parts: Part I introduces the various material models, Part II highlights the finite element modeling of their relevant fracture parameters, and Part III deals with various material damage models. Each part begins with a simple problem with theoretical results compared with finite element results to help readers understand the numerical simulation results.

• Discusses material models such as composite, elastic, elastoplastic, and creep models
• Covers fracture parameters like K, J, C*, and VCCT
• Presents relevant material damage models (ductile, creep, and composite)
• Explores typical and complex problems, including the inclined crack model, penny shaped crack model, compact tension specimen, end-loaded split (ELS) model, double cantilever beam (DCB) model, and notched model

• Includes all modeling files, such as APDL input files, Python code and creep damage subroutine, in the appendixes Written for materials and mechanical engineers, this text addresses and provides solutions to the real-life engineering challenge of damage and fracture in materials and structures.
