3D plate dynamic non-linear analysis
Price US$3,465 Release: To be determined Dynamic non-linear analysis

　Introduction
FORUM8 developed all the functions from pre-processing and calculation engine to post-processing of the new product Engineer's Studio(R)Ver.1.06.03 English Version which is a 3D FEM analysis program. This program analyzes non-linear behavior of structure by modeling with beam elements considering a part of civil engineering and building structure as one bar or continuous plate elements.
　Features
The main features of analysis engine: It has the plate element based on the theory of Reissner- Mindlin in addition to 3D fiber element of UC-win/FRAME(3D) which is high-evaluated. It also allows for the static analysis and dynamic analysis considering those member non-linear and geometric non-linear (large displacement) at the same time.

Plate element can be a laminate structure which has several layers in a thickness direction, the different member kinds and linear or non-linear can be configured individually to each layer. Settlement non-linear constitutive law (dispersed crack model) high-evaluated in the world and developed in concrete lab in Tokyo university is applied to concrete constitutive law which is applied to the plate element. Plate element of this program has derived from the Reinforced Concrete element of UC-win/WCOMD and has been improved in that its thickness can be increased by the addition of multiple layers. Furthermore, it can analyze not only non-linear behavior of in-plane deformation but also that of out-of-plane.
