  • Description: Timber usually has a quasi-brittle behavior characterized by a strong anisotropy according to the grain orientation. In conjunction with steel joints, the timber structure can show a ductile behavior, which is highly desirable when subjected to cyclic loads. It is proposed a numerical framework to simulate a timber structure and to predict the ductile behavior of the structure under different loads, using computational homogenization for timber and phenomenological models for the steel conector. the main objective is to replace this experimental methodology by a numerical framework, in order to obtain new types of hysteretic curves that will help to implement finite elements. This can be used to design connectors within a building with timber structures.

  • Description: Single point incremental forming (SPIF) is a process where a clamped sheet metal is deformed by using a relatively small tool without the need of a die. SPIF has several advantages over traditional forming, such as the high formability attainable by thematerial. The goal of this research is to predict damage and fracture for the SPIF process using the finite element (FE) method. An extended Gurson-type of damage model is implemented in the Lagamine FE code through a fully-implicit integration scheme. The material model parameters are identified based on a specific methodology involving macroscopic and microscopic measurements, using techniques such as digital image correlation and microscopic image analysis. The finite element simulations are performed using a newly developed solid-shell element formulation, specific for shell-type structures. The simulations are compared with experimental measurements for SPIF standard tests.
