Chemical Reactionsf these molecules can now be routinely determined to a high accuracy with the help of quantum chemistry. In many cases, we can evaluate the quality of the calculated results by comparing them with experimental data.

Calculations on Liquids and Solids molecular behavior in a vacuum or in an ideal gas. Chemists, on the other hand, are more interested in characterizing molecules in their natural environment, solutions being perhaps the most important medium. Clearly, if ab initio methods are to make predictions for real chemical problems, they must be able to deal with this issue in some way.

ch graft-IPNs were synthesized by varying the ratios of CoP:PU. Uniaxial tension tests were performed on the resulting IPNs to measure the elastic modulus and strength whereas mode-I fracture toughness was measured under both quasi-static and dynamic loading conditions. A Hopkinson pressure bar was

Tamás Veszprémi,Miklós Fehér s.. The split Hopkinson pressure bar (SHPB) was used for the uniaxial compressive tests at high strain rates ranging from 1,200 to 3,710 s.. The pulse shaping technique was adopted for the SHPB tests to minimize wave dispersion and to facilitate stress equilibrium and constant-strain-rate deformati

Similar experiments were also conducted under dynamic loading using a Hopkinson bar setup. High speed imaging was used to capture the dynamic phenomena. The
