Abstract
The objective in here is to compare the design of a corrugated wire mesh laminate (CWML) with an open-cell mockup by using a uniaxial shear test. This paper depicts the fabrication of CWML specimens by using a transient liquid phase (TLP) skill at low temperatures and a design of a shear testing frame, and then applying uniaxial shear loading. The material used in the fabrication is a 316 stainless steel woven wire mesh with a 0.22-mm wire diameter and 0.95-mm aperture. Tin-alloy (95%Sn–5%Ag) is used as the bonding material in the TLP method, and the designed shear frames are glued with epoxy. The fabricated samples are tested under a uniaxial condition to determine their shear behaviors. Finite element software is employed to model the CWML and study its reaction to mechanical shear loading. The results of the numerical simulation are confirmed by experimental results for the shear loading behavior. Finally, the CWML is concluded to be of an open-cell foam type, and the results of the numerical model show a reasonably linear match to the experimental results on a log-log scale.
