Strength assessment with Iridescent4D
• Semi-automized (strength) assessment → Iridescent4D
• Motivation
• Reduce common user errors while…
• copying data
• repeating boring tasks
• using a general software (HyperView)
• Speed-up evaluation process
• finding hot-spots
• calculating stress gradient
• Create an environment where engineers can focus on underlying causes
• Commercial Softwares are available but…
• Codes applied
• FKM
• SWL99 → not a well-known method (not available)
• additional costs
• not exactly according to our needs
• HyperLife
• An Altair product for strength assessment
• FKM code included
• Under development…
