This is the material properties in Stachiw's book I've been looking
at.
From pages 1036 and 1037
Table 21.1 and 21.2 Specified values of physical properties for each
acrylic casting
(to be verified by testing of specimen from each casting of lot)
(to be certified by the manufacture of material)
-------------------------------------------------------------------------------------
D638* Tensile ultimate
strength
9,000
psi
Modulus of elasticity 400,000 psi ------------------------------------------------------------------------------------------
D695* Compressive yield
strength
15,000
psi
Modulus of elasticity 400,000 psi -------------------------------------------------------------------------------------------
D790* Flexural ultimate strength 14,000 psi =======================================================================================
This also matches up with the data for ASME PVHO-1 Minimums for
cast acrylic in Table 2.5 on page 54.
=======================================================================================
This table compares PVHO minimums with Acrylite
GP cast acrylic
