In many cases, failures do not originate in primary components, but at interfaces such as fasteners, seals, and joints, where tolerance stack-ups, material behavior, and assembly variation interact under operating conditions. This session presents a structured methodology for engineering assembly reliability through analytical modeling, simulation, and design validation. The discussion will cover how tolerance stack-ups, preload variation, thermal expansion mismatch, vibration, and pressure loading contribute to failure modes such as loss of sealing integrity, relaxation of bolted joints, fatigue, and leakage. Approaches to failure prediction will include analytical methods, finite element analysis for stress and deformation, and fluid and thermal modeling where relevant. Emphasis will be placed on identifying critical interfaces, defining boundary conditions, and understanding the limitations of modeling assumptions. The role of design validation will be addressed as a means to correlate models with physical behavior and to close the loop between design, manufacturing, and testing. Using examples from high-risk energy systems, the session will demonstrate how early identification and mitigation of assembly-level failure modes can reduce late-stage redesign, improve safety margins, and enable more predictable system performance across a range of operating conditions.
