CHAP 5 Finite Element Analysis of Contact Problem
– The graph of contact force versus displacement becomes vertical – Both displacement and contact force are unknown in the interface • Objective of contact analysis 1 Whether two or more bodies are in contact 2 Where the location or region of contact is 3 How much contact force or pressure occurs in the interface 4
Contact Stresses and Deformations
Contact Force [N] Stiffness [N/m] ME EN 7960 – Precision Machine Design – Contact Stresses and Deformations 7-18 Effects of Material Combinations • The maximum contact pressure between two curved surfaces depends on: – Type of curvature (sphere vs cylinder) – Radius of curvature – Magnitude of contact force
Basis for Kelvin Contacts - Loranger
force contact is actually delivering the proper signal to the device lead Also, in applications where the Kelvin capability is not used but the same signal is applied to both force and sense contacts, the additional redundant contact provides added assurance that the signal is actually reaching the device lead Improved Thermal Performance

II-7 Military No-Contact Order 3-21b AR 608-18
AR-608-18 • September 2004 (revised May 30, 2006) Page 1 of 3 Military No-Contact Order (3-21b) AR 608-18 (b) Military no-contact orders are similar to civilian temporary restraining orders
Lecture 10: Basics of Atomic Force Microscope (AFM)
Force Modulation Microscopy (FMM): a secondary imaging technique • In FMM mode, the tip is scanned in contact with the sample, and the z feedback loop maintains a constant cantilever deflection (as for constant-force mode AFM) • A periodic vertical oscillation signal is applied to either the tip or the sample The
