The large deformation analysis of a hyperelastic tensile test sample

This example shows the static analysis of a tensile test sample made of rubber. The dimensions of the sample are shown in the following figure. The thickness of the sample is 1.5mm. Using the symmetry, only 1/8 of the sample is analyzed. After solving the 1/8 model, the results of the full model can be … Continue reading The large deformation analysis of a hyperelastic tensile test sample

The application of contact elements: A bolted beam-column connection

In this post, we are going to explore the application of CONTA174 (i.e. 3D 8-node face-face contact element). CONTA174 is used to represent contact and sliding between 3D target surfaces and a deformable surface defined by this element. It can be used for both pair-based contact and general contact. In the case of pair-based contact, … Continue reading The application of contact elements: A bolted beam-column connection

Non-linear analysis of a point-fixed glass curtain wall cable-truss structure

Fig.1 Typical glass curtain walls Some assumptions and simplifications in this problem: Elastic materials Cables are modeled using LINK10 elements with the tension-only option Trusses are modeled using BEAM44 (or BEAM188) elements The glass wall is modeled using SHELL63 elements. Wind load distributes evenly on the surface. The aim of this problem is to calculate … Continue reading Non-linear analysis of a point-fixed glass curtain wall cable-truss structure

Nonlinear analysis of a cable-membrane structure: from shape-finding to static and modal analysis

Fig.1. A typical cable-membrane structure The following assumptions are made in this example: Cables are discretized using LINK10 elements. The membrane is discretized using triangular SHELL41 elements with 'cloth' feature turned on. No slip between cables and membrane. The material complies with Hooke’s Law. The material is orthotropic and elastic. The two principal axes of … Continue reading Nonlinear analysis of a cable-membrane structure: from shape-finding to static and modal analysis

Elastic-plastic analysis of a reinforced concrete slab strengthened by a carbon fiber sheet

A reinforced concrete slab can be strengthened by adhering carbon fiber sheets to the tension side. This is a common practice in concrete structure reinforcement (as shown in Fig.1) Fig.1. Carbon fiber reinforcement. In this problem, the reinforced concrete slab is simply supported. A carbon fiber sheet is attached to the lower surface of the … Continue reading Elastic-plastic analysis of a reinforced concrete slab strengthened by a carbon fiber sheet
