The paper details a methodology for modeling fatigue-induced crack growth in the Forged Weld Zone (FWZ) of an Electric Resistance Welding (ERW) process. Utilizing ANSYS Static Structural and APDL modules, it applies strain-life analysis and calculates the intensity factor KI. The study focuses on a 20" API 5L Gr B carbon steel pipe under specific pressure and temperature conditions, starting from an induced crack. It integrates existing literature while proposing innovative variants, and employs two load cycles to analyze crack propagation using the Paris equation.

Chamalu tells the story of a young woman's initiation into Andean wisdom traditions under the guidance of Chamalu, a Quechua shaman. The sacred way of the heart, he tells her, is a spiritual journey that must be undergone by anyone who aspires to be a Wanderer--a person who transcends illusion and embraces primal reality, unmediated by religious doctrine or intellectual constructs. The woman asks him to show her how to release herself from the emotional pain that paralyzes her, and gradually, over a series of meetings, Chamau reveals to her the secret of reconnecting with the spirits of the ancestors and of Pachamama, Mother Earth. Presented as a series of conversations, Chamalu encompasses teachings that can be lived and experienced by anyone who truly desires to learn. Simply told in language that appeals directly to the heart, Chamalu allows the reader to experience Andean shamanic teachings based on the ancient Inca heritage of wisdom, inner power, simplicity, and joy.
