Mechanical behavior and numerical analysis of corrugated wire mesh laminates
최정호,Krishna Shankar,Murat Tahtali 대한기계학회 2012 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.26 No.1
The objective is to show a possibility of corrugated wire mesh laminate (CWML) structure for bone application. CWML is a part of open-cell structures with low density and high strength built with bonded mesh layers. Specimens of CWML made of 316 stainless steel woven meshes with 0.22 mm wire diameter and 0.95 mm mesh aperture, bonded by transit liquid phase (TLP) at low temperatures, were fabricated and tested under quasi-static conditions to determine their compressive behavior with varying numbers of layers of the sample. The finite element software was used to model the CWML and studied their response to mechanical loading. Then, the numerical model was confirmed by the tested sample. Consequently, CWML specimens were reasonably matched with the human tibia bone ranged over apparent density from 0.05 to 0.08 g/cm3 in Young’s modulus and from 0.05 to 0.11 g/cm3 in compressive yield strength. The CWML model can have the potential for bone application.

The objective in this paper presents an attempt to understand and characterize the behavior of corrugated wire mesh laminates (CWML) under transverse compression loading. Specimens of the CWML are made of stainless steel type 316 woven metal and crossed points in the mesh are bonded with eutectic at low temperature. Experimental testing is conducted on several samples of single layer, two layer, and four layer wire mesh laminates under transverse compression The load deflection behaviors of the single and multi layer laminates observed in the tests are analyzed. Therefore, it does provide significant insight into aspects that influence the deformation behavior of CWML.
