Abstract: Fields of pressure are considered in heterogeneous material under pulse irradiation. Method is suggested for the calculation of efficient Gruneisen's factor for heterogeneous material with laminated microballoons under irradiation. The heterogeneous material is considered with two distinctive sizes of filler. Component's technological porosity is taken into account. Dependency of Gruneisen's factor on parameters of filler is examined and compared with experimental data. Pressure profiles are calculated for pulse irradiated heterogeneous material.
