SUMMARY:Two Days Hands on Workshop on Elasto-Plastic Fracture Mechanics (EPFM)
DESCRIPTION:Two Days Hands on Workshop on Elasto-Plastic Fracture Mechanics (EPFM)\n3D Crack Growth : Theory & Simulation\n5-6th July 2024 @Virtual Engineering\, Rajajinagar\, Bangalore \nAbout Workshop\nThis workshop introduces theoretical fracture mechanics – covering Elastic-plastic fracture mechanics which applies to materials that exhibit time-independent\, nonlinear behavior (i.e.\, plastic deformation). Two elastic-plastic parameters i.e.\, crack-tip-opening displacement (CTOD)\nand the J contour integral describes crack-tip conditions in elastic-plastic materials\, and each can be used as a fracture criterion. Critical values of CTOD or J give nearly size-independent measures of fracture toughness\, even for relatively large amounts of crack-tip plasticity. EPFM approach with dynamics of crack initiation\, propagation\, and failure. \nWorkshop also explains factor in predicting the Stress Intensity Factor (SIF); Consideration of crack geometries\, crack growth laws\, time\, cycle dependent combined with time\, temperature dependent crack growth; Fatigue life calculation under simple\, non-proportional\, transient\, spectrum\, hold\, combination and load schedules\, further fatigue life\, SIF history life calculation. Simulated Observed \nWorkshop will be a hybrid studies of fracture mechanics theory and 3D Crack Growth Simulations / computational fracture mechanics with hands on experience. Users are encouraged to bring their problem statements (with EA) performed and experts will guide to simulate the fracture studies during the workshop. \nTopics Covered (Theory & Practical)\n\nCrack-Tip-Opening Displacement: Displacement at the original crack tip and displacement at the intersection of a 90°  vertex with the crack flanks\, crack-mouth-opening displacement.\nThe J Contour Integral: Nonlinear Energy Release Rate\, J as a Path-Independent Line Integral\, J as a Stress Intensity Parameter\, The Large Strain Zone\, Laboratory Measurement of J. Relationships Between J and CTOD\, Crack-Growth Resistance Curves\, Stable and Unstable Crack Growth\, Computing J for a Growing Crack\nJ -Controlled Fracture – Stationary Cracks\, Controlled Crack Growth\, Crack-Tip Constraint Under Large-Scale Yielding\, The Elastic T Stress\, J – Q Theory\, The J – Q Toughness Locus\, Effect of Failure Mechanism on the J – Q locus\, Scaling Model for Cleavage Fracture\, Failure Criterion\, Three-Dimensional Effects\, Application of the Model\, Limitations of Two-Parameter Fracture Mechanics.\nCrack Growth Rate Models For Subcritical Crack Growth: Paired Crack growth rate and R-ratio models\, Growth Rate Models : Paris\, bilinear Paris\, sigmoidal\, hyperbolic sine\, Stress ratio model : Walker\, Newman NASGRO Equation.
