What this episode covers

Discover why holes triple structural stress — and how a simple drilled hole can multiply local stresses by 3x or more, turning safe designs into sudden failure points. We break down stress concentration factors (Kt), the classic circular hole in tension case where Kt ≈ 3, elliptical holes, notches, finite width corrections, fatigue crack initiation at holes, and real mechanical engineering strategies to reduce or account for them using fillets, reinforcements, and proper analysis.Keywords: why holes triple structural stress, stress concentration factor, stress concentration hole, circular hole stress riser, Kt factor mechanical engineering, hole in plate tension, stress concentration fatigue, notch effect structural design, reducing stress concentration, fillet radius stress, mechanical engineering stress analysis, fracture at holes, fatigue failure holes, stress riser design, structural integrity holesDiscover why holes triple structural stress — and how a simple drilled hole can multiply local stresses by 3x or more, turning safe designs into sudden failure points.

NEWMORROW SESSIONS - A PodCast Series on the Future of Hospitality Mario C. Bauer, Florian Schneider, Axel Weber & Dr. Tillman Bardt The Newmorrow PodCast is more than a podcast — it's a platform for open dialog on the future of our business, a platform for those building what doesn’t exist yet. Here, we share and embrace our passion for the hospitality industry, but we won’t romanticize the journey. We ask the tough questions, confront uncomfortable truths, and prepare for a future that resists easy answers. We believe that the tougher and wilder times become, the more openly, honestly and humanely people need to talk to each other and act together. We believe, openness, togetherness, and truthfulness should also be cornerstones of a professional community to develop our utopian idea of „open source“. This is a space where visionaries don’t just imagine the future — they wrestle with the paradoxes that shape it: success vs. happiness, data vs. instinct, stability vs. reinvention. Join leaders, entrepreneurs, and thinkers as they share not what made them — but what’s actively shaping them, now and next. So tune in Hyperfluent Hypio Hyperfluent transmits straight from the heart of Hyperliquid, where culture, creativity, and capital converge. Anchored by the architects of Hypio—the decentralized cultural virus—each episode archives the minds engineering the blockchain built to house all finance. These conversations are traceable artifacts in HyperEVM’s evolution: not just what’s being built, but why it matters, how it mutates, and where it’s taking us next. Listen in for the blueprints, the blind spots, and the narrative weapons shaping tomorrow’s markets.Hyperfluent: learn the language, ride the wave, spread the strain.
