🧲 How does shell thickness affect adhesion? Elastomeric hemispherical shells show: ⚖️ Thick → Hertz-JKR-like pull-off 📉 Thinner → weaker adhesion 📈 Ultra-thin → adhesion increases again! 🧪 Experiments + FEM agree 🔗 Read: doi.org/10.1016/j.eml.… #adhesion #mechanics

Elastomeric hemispherical shells show:
⚖️ Thick → Hertz-JKR-like pull-off
📉 Thinner → weaker adhesion
📈 Ultra-thin → adhesion increases again!
🧪 Experiments + FEM agree
