plywood coefficient of thermal expansion

the coefficients ci thermal expansion of wood and wood products Little data are available on the thermal expansion of natural solid wood, plywood, impreg, compreg, and papreg, and none on staypak, and hydro- lyzed wood, plastics and laminated sheets. Consequently, the studies here- in reported were 

thermal properties - Mets? Wood thermal. PROPERTIES. Kerto? products can be used in the same conditions as standard conifer plywood. The thermal conductivity coefficient λ for wood products is moisture dependent. The thermal conductivity coefficients for Kerto products thermal expansion in the direction of wood fibres is in the range from.

Solved: simulation Error: Some components are using a material Solved: While doing a thermal simulation (no stress) I get an "Error: Some components are using a material with These pictures may help, where you can see the highlighted thermal properties for "thermal Conductivity", "thermal expansion coefficient" and "Specific Heat" in A work-around to use the "thermal_Conductivity" of "plywood" in a thermal simulation could be achieved by
